Abstract
The invention mainly relates to a support tube combined thrust for laparoscopic operation. The support tube combined thruster for laparoscopic operation comprises a puncture sleeve, a guide wire, an outer conversion sheath, a guide wire implanted core and a support tube thrusting core. The outer conversion sheath is provided with a through cavity, the guide wire implanted core can be inserted into the through cavity of the outer conversion sheath, the outer wall of the guide wire implanted core is closely attached to the inner wall of the outer conversion sheath, the guide wire implanted core is axially provided with two guide wire through cavities, the support tube thrusting core can be inserted into the through cavity of the outer conversion sheath and axially provided with two guide wire through cavities, the outer wall of the guide wire implanted core is closely fitted to the inner wall of the outer conversion sheath, and the support tube thrusting core is longer than the guide wire implanted core. Components are combined to use, operation difficulty can be reduced, operation time is shortened, operation efficiency and operation quality are improved, workload of medical staff can be reduced, and pain and burden of patients can be alleviated.
Description
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 becoming surgical field of laparoscopic surgery, during operation on ureter, due to ureter be positioned at peritoneum after darker specific position, especially when carrying out laparoscopic surgery, ureter rack tube to insert difficulty larger, require very high to the proficiency level of Urology Surgery doctor, and cause operating time longer, the safety of operation and reliability reduce.
Summary of the invention
The present invention, for solving problems of the prior art, provides a kind of ureter bracket tube propeller, can reduce operating difficulty, shortens operating time, improves procedure efficiency and quality, reduces medical worker's workload, more alleviates misery and the burden of patient.
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 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 inserts core fits tightly with the inwall of conversion 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, support tube advance core be provided with two seal wire cavities vertically, support tube advances the length of core to be greater than the length that seal wire inserts core, puncture casing has sealing shell fragment.
Beneficial effect of the present invention:
One, laparoscopic surgery support tube built-up propeller provided by the invention, first seal wire is inserted core and penetrate conversion epitheca, again the conversion epitheca of inserting core with seal wire is inserted puncture casing, the space be in communication with the outside when opening the sealing shell fragment of puncture casing like this becomes from original puncture casing the seal wire cavity that seal wire inserts core and support tube propelling core, sealing obviously strengthens, and significantly improves the safety of operation.
Two, each assembly of this device is combined with each other, and can reduce operating difficulty, shortens operating time, improves procedure efficiency and surgical quality, can not only reduce the workload of medical worker, more can alleviate misery and the burden of patient.

Detailed description of the invention
As shown in the figure: laparoscopic surgery support tube built-up propeller, comprise puncture casing 1(English name: trocar) and 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 inserts core 3 fits tightly with the inwall of conversion 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, support tube advance core 4 be provided with two seal wire cavities vertically, support tube advances the length of core 4 to be greater than the length that seal wire inserts core 3, puncture casing 1 has sealing shell fragment.
When carrying out laparoscopic surgery, first puncture casing 1 is inserted abdominal cavity to fix, as shown in Figure 1, then seal wire is inserted core 3 and penetrate conversion epitheca 2, as shown in Figure 2, the conversion epitheca 2 of inserting core 3 with seal wire is inserted puncture casing 1, again two seal wire cavities that seal wire 5 inserts core 3 along seal wire are extended to intraperitoneal, one arrives bladder, one arrives renal pelvis, as shown in Figure 3, seal wire 5 is extracted seal wire and is inserted core 3 after having inserted, again the two ends of support tube 6 to be enclosed within respectively on seal wire 5 and to enter abdominal cavity along seal wire 5, after support tube 6 is all through seal wire 5, two seal wires 5 are stretched out from the aperture support tube 6, as shown in Figure 4, the seal wire 5 stretched out continues to penetrate two seal wire cavities that support tube advances core 4, then core 4 roof support pipe 6 is gradually advanced with support tube, as shown in Figure 5, seal wire 5 is extracted after support tube 6 is inserted completely, namely inserting of laparoscopic surgery medium-height trestle pipe 6 is completed, as shown in Figure 6.
Laparoscopic surgery support tube built-up propeller provided by the invention, first seal wire is inserted core 3 and penetrate conversion epitheca 2, again the conversion epitheca 2 of inserting core 3 with seal wire is inserted puncture casing 1, the space be in communication with the outside when opening the sealing shell fragment of puncture casing 1 like this becomes from original puncture casing 1 two seal wire cavities that seal wire inserts core 3 and support tube propelling core 4, sealing obviously strengthens, and significantly improves the safety of operation; Each assembly of this device is combined with each other, and can reduce operating difficulty, shortens operating time, improves procedure efficiency and surgical quality, can not only reduce the workload of medical worker, more can alleviate misery and the burden of patient.
