The upper force body comprises an upper forcep handle, an upper forcep rod and an upper forcep head, the upper forcep rod is fixedly connected with the upper forcep handle, is integrally tubular and is hollow, and the upper forcep head is located at a front end opening of the upper forcep rod. The lower forcep body comprises a lower forcep handle, a lower forcep rod and a lower forcep head, the lower forcep rod is fixedly connected with the lower forcep handle, is integrally tubular and is hollow, and the lower forcep head is located at a front end opening of the lower forcep rod. A water inlet is formed in the position, close to the upper forcep handle, of the upper forcep rod, a suction opening is formed in the position, close to the lower forcep handle, of the lower forcep rod, a hollow pin for rotational connection and communicating is arranged between the upper forcep rod and the lower forcep rod, and one end of the hollow pin is located on one side face of the upper forcep body and provided with a pressing valve for opening and closing the hollow pin. According to the bladder lithotomy forceps, multiple functions of the hollow forcep rods are effectively combined, the bladder lithotomy forceps can serve as flushing and suction channel pipes and can also serve as gravel channel pipes for picking fine stone and force arms for picking the stone, and the bladder lithotomy forceps are convenient to use, simple in structure and low in cost.

Description

Lithotomy forceps

Technical field

The present invention relates to technical field of medical instruments, specifically a kind of lithotomy forceps.

Background technology

Lithotomy forceps is a kind of apparatus commonly used in the surgical operation for take calculus, is used to grip calculus.Existing bladder takes Stone pincers are made up of clamp handle and binding clip, and simple structure carries out calculus gripping using Mechanics of Machinery principle, and binding clip is broadly divided into larger The rubber binding clip of coefficient of friction and the binding clip with formation cavity after clamping, but in surgical procedure, because calculus shape is not advised Then, the characteristic such as hard but also crisp not only, either rubber binding clip or can form the binding clip of cavity, all it may happen that staff is firmly excessive Calculus-smashing is caused, more Microlithiasis fragment is easily formed so as to lead to not effectively clean out after crushing.In addition also just like The bladder renal pelvis stones extraction lens of Chinese patent CN 101214163B, mainly by lithotomy forceps clip assembly, lithotomy forceps folder tube channel, rubble Tube channel, optical-fibre channel pipe, intake tunnel pipe and endoscope assembly composition, with fixed calculus, crushed stone, suction rubble and The effect of rubble is absorbed, can be used for most cases takes calculus surgical operation, but this takes Shi Jing and there is operation and requires higher, knot More complicated, the relatively costly problem of structure.

The content of the invention

In order to solve the above technical problems, both being gripped with conventional mechanical mechanics principle it is an object of the invention to provide a kind of Structure, can effectively carry out calculus gripping, but also with the suction ability for taking Shi Jing, splinter of stone and other debris can be absorbed, It is easy to operate, simple structure, lithotomy forceps with low cost.

To reach above-mentioned purpose, technical scheme is as follows：

A kind of lithotomy forceps, including upper clamp and the lower clamp with upper clamp symmetrical configuration, it is characterised in that：On described Caliper includes upper plier handle and the upper plier handle upper claw beam for being fixed with one hollow in a tubular form and the upper pincers being provided with positioned at upper claw beam front port Head, the lower clamp includes lower plier handle and the lower plier handle lower claw beam that is fixed with one hollow in a tubular form and positioned at lower claw beam front port The lower pliers head being provided with, the upper claw beam is provided with water inlet at upper plier handle, and the water inlet front side is provided with and is turned on upper claw beam Inlet regulating valve, the lower claw beam is provided with suction port at the lower plier handle, and the suction port front side is provided with and the conducting of lower claw beam Attraction regulating valve, be provided between the upper claw beam and lower claw beam for rotating the hollow pins that connect and turn on, the hollow pins One end is provided with the push valve for being opened and closed hollow pins positioned at upper clamp one side.

Further, the upper grip head is including the upper grip head body with the semicircular in shape of the fixed one of upper claw beam and is arranged on Upper rubber layer in upper grip head body semicircular inner walls, the lower pliers head include with the semicircular in shape of the lower fixed one of claw beam under Binding clip body and the lower rubber layer being arranged in lower pliers head body semicircular inner walls, the upper grip head body and this body phase of lower pliers head Symmetrically.

Further, the upper grip head surface offers multiple upper grip head bodies and upper rubber layer of running through is used for flushing liquid The first through hole of flowing, the lower pliers head surface offers multiple lower pliers head bodies and lower rubber layer of running through is used for flushing liquid stream The second dynamic through hole.

Further, the upper rubber layer surface is provided with multiple for clamping and anti-skidding upper projection, the lower rubber layer Surface is provided with multiple for clamping and anti-skidding lower convexity.

Further, the push valve include valve body, be fixedly connected with the valve body and through the sleeve in hollow pins, set The block that is adapted in sleeve and with sleeve lining, fixed positioned at the block fixed spring in axial direction one end and with the spring other end And the interior button being placed in valve body.

Further, the perforation offered through sleeve is located in upper claw beam in the sleeve wall.

Beneficial effects of the present invention：

1st, lithotomy forceps of the invention, is designed using Mechanics of Machinery theory structure, effectively combines many of hollow claw beam Weight function, you can as the suction tube channel rinsed with attract, can be used as absorbing the broken of Microlithiasis fragment and other debris again Stone tube channel, can also be used as to grip the arm of force of calculus, effectively realize the function needs of gripping calculus in operation.

2nd, the present invention in push valve, when pressing push valve, closed between upper claw beam and lower claw beam and isolated, at the same open into Water regulating valve and attraction regulating valve, can make claw beam front port, lower claw beam front port, water inlet and suction port to form flushing and follow Loop back path；When unclamping push valve, connected between upper claw beam and lower claw beam, simultaneously close off inlet regulating valve and open attraction regulation Valve, so as to the larger calculus suction-operated to being contacted at upper claw beam front port and lower claw beam front port, is greatly improved The steadiness of calculus is gripped, the convenience of gripping calculus is also increased.

3rd, the binding clip in the present invention, binding clip semicircular structure design can prevent other tissues to bladder mucosa etc. from causing to damage Wound, while the rubber layer in semicircular inner walls can avoid for calculus being caught broken increase operating time, the multiple that rubber layer surface is provided with Anti-skid bulge can effectively prevent calculus from being slid when gripping.

4th, lithotomy forceps of the invention, fully with reference to ergonomics, operation is easy, easy to use, while structure is simple It is single, it is with low cost.
