Abstract
The invention provides a magnetic anastomat device for single-port laparoscopic colorectal resection, comprising a nail-shaped magnetic nail anvil head, a magnetic nail anvil block with a central groove and matched with the magnetic nail anvil head, and a cylindrical in vitro permanent magnet matched with the magnetic nail anvil head; the magnetic nail anvil head can be well positioned by the magnetic attraction between the in vitro permanent magnet and the magnetic nail anvil head, and simultaneously, the intestinal tract can be pulled to facilitate resection of the near end of the intestinal tract; after the intestinal tract is resected, the stub end of the intestinal tract is anastomosed by the magnetic attraction between the magnetic nail anvil head and the magnetic nail anvil block; and after being combined, the magnetic nail anvil head and the magnetic nail anvil block finally fall off in the intestinal cavity and are excreted along with feces to avoid inconvenience and discomfort of a patient when left in vivo. Thereof, the invention avoids dual-port colorectal resection and needs only a single port, thus meeting the requirements of patients and doctors for a super minimally invasive surgery.
Description
Technical field
The invention belongs to technical field of medical instruments, be specifically related to a kind of magnetic anastomat device that is used for single-hole laparoscopic knot proctectomy.
Background technology
Minimally Invasive Surgical Technology is the important trend of current surgical field development, and its principle is that the method with small invasion and attack reaches the operative treatment purpose.Based on the patient wound beauty treatment requirements at the higher level and doctor are pursued a minimizing stomach wall stamp mouthful complication purpose, reduce stabbing mouthful number and adopt dexterous manipulation more to become the emphasis direction of minimally invasive surgery doctor work, is the practice result that surgeon is pursued the ultra micro woundization and developed recently gets up through the umbilicus single-hole laparoscopic surgery.After umbilicus single-hole laparoscopic surgery technology was introduced pneumoperitoneum by the umbilical opening puncture, the puncture tube of inserting a plurality of operations of portability duct was by operating duct introducing operating theater instruments and luminaire to finish operation technique.Such modus operandi is all succeedd in operation such as gallbladder removal, appendectomy and oophorectomize, has satisfied the patient requirements at the higher level and the doctor of wound beauty treatment reduced the pursuit that stomach wall stabs the card complication.
Yet current can't the knot in the proctectomy at single-hole laparoscopic of such expected results realized.Coincide because need to tie the rectum stump in the knot proctectomy process, and there is defective in the design of current anastomat, can't finish coincideing of knot rectum stump by laparoscopically stamp card.Therefore, tie coincideing of rectum stump, no matter single-hole laparoscopic still is traditional peritoneoscope, need do little otch on focus flank rectus side and carry out.It is not single hole that such result makes so-called single-hole laparoscopic knot proctectomy, is actually diplopore, can not satisfy patient and the doctor requirement to operation ultra micro woundization.
Summary of the invention
In order to overcome the deficiency that above-mentioned prior art exists, the object of the present invention is to provide a kind of magnetic anastomat device that is used for single-hole laparoscopic knot proctectomy, avoided the proctectomy of diplopore mode, only needed single hole to get final product, satisfied patient and doctor requirement operation ultra micro woundization.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of magnetic anastomat device that is used for single-hole laparoscopic knot proctectomy comprises the magnetic nail anvil head 2 of spike and the adaptive with it magnetic nail anvil seat 3 that has central recess 4, also comprises the outer permanent magnet 1 of the column that matches with magnetic nail anvil head 2 in addition.
Described external permanent magnet 1, magnetic nail anvil head 2 and magnetic nail anvil seat 3 are the rubidium ferrum boron magnetic material that the surface has nickel dam, and nickel layer thickness is 1mm.
Simultaneously can also carry out tractive by utilizing between external permanent magnet 1 and the magnetic nail anvil head 2 magnetic attracting force to carry out good location, the near-end excision of intestinal tube is more easily gone intestinal tube to magnetic nail anvil head 2; After treating the intestinal tube excision, and utilize the magnetic attracting force between magnetic nail anvil head 2 and the magnetic nail anvil seat 3 to finish coincideing of intestinal tube stump; Magnetic nail anvil head 2 is with after magnetic nail anvil seat 3 combines, finally can come off in enteric cavity, excrete in company with feces, avoiding staying in the body brings inconvenience and discomfort to patient, has avoided the proctectomy of diplopore mode thus, only needs single hole to get final product, satisfied patient and doctor requirement to operation ultra micro woundization, in addition, external permanent magnet 1, magnetic nail anvil head 2 and magnetic nail anvil seat 3 surfaces all are coated with nickel, have increased biocompatibility.
Description of drawings
Fig. 1 is a structural representation of the present invention, and Fig. 1 (a) is the structural representation of external permanent magnet 1, and Fig. 1 (b) is the structural representation of magnetic nail anvil head 2, and Fig. 1 (c) is the structural representation of magnetic nail anvil seat 3.
The specific embodiment
The present invention will be described in more detail below in conjunction with accompanying drawing.
As shown in Figure 1, the magnetic anastomat device that is used for single-hole laparoscopic knot proctectomy, comprise the magnetic nail anvil head 2 of spike and the adaptive with it magnetic nail anvil seat 3 that has central recess 4, also comprise the outer permanent magnet 1 of the column that matches with magnetic nail anvil head 2 in addition.Described external permanent magnet 1, magnetic nail anvil head 2 and magnetic nail anvil seat 3 are the rubidium ferrum boron magnetic material that the surface has nickel dam, and nickel layer thickness is 1mm.
Operation principle of the present invention is: at first finish the operation in early stage of single-hole laparoscopic knot proctectomy, by magnetic nail anvil head 2 is put into the near-end of waiting to excise intestinal tube, magnetic attracting force between magnetic nail anvil head 2 and the external permanent magnet 1 is finished the location of location magnetic nail anvil head 2, finishes the excision of intestinal tube near-end simultaneously; After treating lesion resection, magnetic nail anvil head 2 leans out the intestinal tube near-end, and places a coil 6 at its spike head, is equivalent to the purse string suture of traditional operation, once more magnetic nail anvil seat 3 is put into assigned address subsequently; Utilize magnetic attracting force between magnetic nail anvil head 2 and the magnetic nail anvil seat 3 to finish coincideing of intestinal tube stump at last; Magnetic nail anvil head 2 finally can come off in enteric cavity with after magnetic nail anvil seat 3 combines, and excretes in company with feces.
