Abstract
The utility model mainly relates to a stand tube built-up propeller for laparoscopic surgery. The stand tube built-up propeller for the laparoscopic surgery comprises a trocar cannula and a guide wire. The propeller further comprises a conversion outer sheath, a guide wire implanting core and a stand tube propelling core. The conversion outer sheath is provided with a through cavity. The guide wire implanting core can be inserted into the through cavity of the conversion outer sheath, and the outer wall of the guide wire implanting core is tightly attached to the inner wall of the conversion outer sheath. Two guide wire through cavities are formed in the guide wire implanting core in the axial direction. The stand tube propelling core can be inserted into the through cavity of the conversion outer sheath, and the outer wall of the guide wire implanting core is tightly attached to the inner wall of the conversion outer sheath. Two guide wire through cavities are formed in the stand tube propelling core in the axial direction. The length of the stand tube propelling core is larger than the length of the guide wire implanting core. Components of the stand tube built-up propeller can be mutually combined for use, so that the difficulty of the surgery can be reduced, time of the surgery is shortened, efficiency and quality of the surgery are improved, workload of medical staff can be reduced, and pains and burdens of patients can be reduced.
Description
Technical field
This utility model belongs to medical instruments field, relates 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.
The utility model content
This utility model provides a kind of ureter bracket tube propeller for solving problems of the prior art, can reduce operating difficulty, shorten operating time, improve operation efficient and quality, reduce medical worker's workload, more alleviated patient's misery and burden.
The technical scheme in the invention for solving the above technical problem 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.
The beneficial effects of the utility model:
The laparoscopic surgery that one, this utility model provide 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.
The laparoscopic surgery that this utility model provides 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.
