Laparoscopic surgery support tube built-up propeller
Technical field
The invention belongs to medical instruments field, relate generally to a kind of laparoscopic surgery support tube built-up propeller.
Background technology
The mathematical development trend that becomes surgical field of laparoscopic surgery, during operation on ureter, because ureter is positioned at darker specific position behind the peritoneum, especially when carrying out laparoscopic surgery, ureter rack tube to insert difficulty bigger, proficiency level's requirement to the Urology Surgery doctor is very high, and causes operating time longer, and the safety of operation and reliability reduce.
Summary of the invention
The present invention provides a kind of ureter bracket tube propeller for solving problems of the prior art, can reduce operating difficulty, shortens operating time, improves operation efficient and quality, reduces medical worker's workload, has more alleviated patient's misery and burden.
The technical scheme that the present invention solves the problems of the technologies described above employing is: laparoscopic surgery support tube built-up propeller, comprise puncture casing and seal wire, described propeller also comprises the conversion epitheca, seal wire inserts core and support tube advances core, described conversion epitheca has a cavity, seal wire is inserted core and can be inserted in the cavity of conversion epitheca, and the outer wall that seal wire is inserted core fits tightly with the inwall of changing epitheca, seal wire is inserted core and is provided with two seal wire cavities vertically, described support tube advances core can insert in the cavity of conversion epitheca, and the outer wall that seal wire is inserted core fits tightly with the inwall of changing epitheca, what support tube advanced core is provided with two seal wire cavities vertically, and support tube advances the length of core to insert the length of core greater than seal wire.
Beneficial effect of the present invention:
One, laparoscopic surgery provided by the invention support tube built-up propeller, earlier seal wire is inserted core and penetrate the conversion epitheca, to have seal wire again and insert the conversion epitheca insertion puncture casing of core, the space that is in communication with the outside when opening the sealing shell fragment of puncture casing becomes the seal wire cavity that seal wire is inserted core and support tube propelling core by original puncture casing like this, sealing obviously strengthens, and significantly improves the safety of operation.
Two, each assembly of this device use that mutually combines can reduce operating difficulty, shortens operating time, improves operation efficient and operation quality, can not only reduce medical worker's workload, more can alleviate patient's misery and burden.

The specific embodiment
As shown in the figure: laparoscopic surgery support tube built-up propeller, comprise puncture casing 1(English name: trocar) with seal wire 5, described propeller also comprises conversion epitheca 2, seal wire inserts core 3 and support tube advances core 4, described conversion epitheca 2 has a cavity, seal wire is inserted core 3 and can be inserted in the cavity of conversion epitheca 2, and the outer wall that seal wire is inserted core 3 fits tightly with the inwall of changing epitheca 2, seal wire is inserted core 3 and is provided with two seal wire cavities vertically, described support tube advances core 4 can insert in the cavity of conversion epitheca 2, and the outer wall that seal wire is inserted core 3 fits tightly with the inwall of changing epitheca 2, what support tube advanced core 4 is provided with two seal wire cavities vertically, and support tube advances the length of core 4 to insert the length of core 3 greater than seal wire.
When carrying out laparoscopic surgery, earlier puncture casing 1 being inserted the abdominal cavity fixes, as shown in Figure 1, then seal wire is inserted core 3 and penetrate conversion epitheca 2, as shown in Figure 2, to have seal wire and insert the conversion epitheca 2 insertion puncture casing 1 of core 3, two seal wire cavities that seal wire 5 is inserted core 3 along seal wire extend to intraperitoneal again, one arrives bladder, one arrives renal pelvis, as shown in Figure 3, extracts seal wire after seal wire 5 is inserted and finished and insert core 3, again the two ends of support tube 6 are enclosed within respectively on the seal wire 5 and along seal wire 5 and enter the abdominal cavity, after treating that support tube 6 all passes seal wire 5, two seal wires 5 are stretched out from the aperture on the support tube 6, as shown in Figure 4, the seal wire 5 that stretches out continues to penetrate two seal wire cavities that support tube advances core 4, advance core 4 roof support pipe 6 gradually with support tube then, as shown in Figure 5, treat to extract seal wire 5 after support tube 6 is inserted fully, namely finish inserting of laparoscopic surgery medium-height trestle pipe 6, as shown in Figure 6.
Laparoscopic surgery provided by the invention support tube built-up propeller, earlier seal wire is inserted core 3 and penetrate conversion epitheca 2, to have seal wire again and insert the conversion epitheca 2 insertion puncture casing 1 of core 3, the space that is in communication with the outside when opening the sealing shell fragment of puncture casing 1 becomes two seal wire cavities that seal wire is inserted core 3 and support tube propelling core 4 by original puncture casing 1 like this, sealing obviously strengthens, and significantly improves the safety of operation; The use that mutually combines of each assembly of this device can reduce operating difficulty, shortens operating time, improves operation efficient and operation quality, can not only reduce medical worker's workload, more can alleviate patient's misery and burden.
