Description

Peritoneoscope T manages inserter

Technical field

This utility model belongs to medical apparatus and instruments, a kind of T pipe embedded device that uses in the laparoscopic surgery that is mainly used in.

Technical background

At present, the laparoscopic common bile duct exploration art is carried out widely in China hospitals at different levels.Finish after bile duct exploration gets stone, usually need the T pipe is presented to and sew up bile duct wall in the common bile duct again, can prevent complication such as gallbladder leakage with biliary drainage to external like this.And insert the T pipe in the peritoneoscope condition certain difficulty is arranged, particularly common bile duct does not obviously increase under the thick situation.Be not specifically designed to the device that the T pipe is inserted in the existing laparoscopic instrument, surgical doctor is usually clamped T pipe inserter with mosquito forceps and is sent into by force.Cause common bile duct tongue tear and other unexpected damages easily like this, operation is difficulty relatively also.

The utility model content

The purpose of this utility model is to provide a peritoneoscope T pipe inserter, and described inserter can solve and insert the difficult and inconvenient of T pipe under the peritoneoscope condition.

For achieving the above object, scheme of the present utility model is: a trocar sheath is set, is with a movably inner sleeve in its tube chamber, be inserted in the handle of a T pipe in the internal canula lumen, the arm of inserting of T pipe curls under the deposit state and sends in the bile duct, and inserts the arm ejection when managing in promoting.

Further scheme comprises: spring of cover between inner sleeve outer wall and outer sleeve inner wall, described spring is compression spring or extension spring.

Adopt such scheme, can be convenient under the peritoneoscope condition, safety, fast T is managed inserter and insert common bile duct, thus realized the purpose of this utility model.

Scheme below by embodiment and accompanying drawing more detailed description the application.

The specific embodiment

Be illustrated in figure 1 as the T pipe that usually uses in the medical procedure, the handle 1 that comprises the T pipe, and with the arrangement of 1 one-tenth T font of handle insert arm 2, inserting arm is the two-section short tube, usually will insert arm puts into the bile duct of incision and sews up bile duct again, as previously mentioned, insert arm 2 and under the peritoneoscope condition, seem very difficult, so design peritoneoscope T pipe inserter as described in Figure 2 is a task of the present utility model.As shown in Figure 2, T pipe inserter comprises a trocar sheath 3, and the tube wall gap portion that is with inner sleeve 4, two pipes in its tube chamber is equipped with spring, and spring is extension spring or compression spring, and the spring difference is housed, and the structure of pipe is slightly had any different.Be illustrated in figure 3 as the T pipe inserter that is equiped with extension spring 5, in the tube chamber of inner sleeve 4, can include the handle 1 of T pipe in, the end for the treatment of handle 1 is up carried after exposing the upper shed of inner sleeve 4 again, two to insert arm 2 deposit that curls in the one section cavity that enters trocar sheath 3 stand-by, the bottom of described inner sleeve 4 has a circle projection 6 to cooperate with the trocar sheath inner chamber, the top of inner sleeve 4 also is fixed with a protruding circle 7, axial location as extension spring 5, extension spring is enclosed within on the outer tube wall of inner sleeve 4, the upper end of inner sleeve 4 has a finger-like push pedal 9 to be connected with end thread or is inserted in spring 5 back fastening means connections, on the mouth of pipe of trocar sheath 3, be provided with a pipe cap 10, be connected with the mouth of pipe with screw thread, the two ends of extension spring are connected with pipe cap 10 with protruding circle 7 respectively, the upper end of trocar sheath 3 is provided with a pair of finger round handle 11 symmetrically, holds trocar sheath to pierce into two fingers.

Be after promoting the finger-like push pedal of inner sleeve 4 upper ends as shown in Figure 4, become two of folded state to insert arm 2 and rely on elastic stretch, this also is to insert the duty of arm 2 in common bile duct, after inner sleeve 4 is released and is inserted arm 2, contract after being in the spring 8 of extended state, inner sleeve is returned to original position, the location of the inner sleeve 4 of this structure mainly relies on a circle projection 7, make force analysis, inner sleeve 4 is subjected to active force upwards and is delivered to extension spring 8 through projection 7, power passes on the set pipe cap 10 of the mouth of pipe of trocar sheath 3 behind the compression spring, and pipe cap 10 is fixed on the trocar sheath, forms seal force system.

Zhuan She spring is compression spring 12 as shown in Figure 2, its structure is slightly different with Fig. 3, fix a protruding circle 13 in inner sleeve 4 upper ends, have a segment distance place to fix at the inner chamber of trocar sheath 3 from port and be inserted in compression spring 12 between one second protruding circle 14, the two protruding circles, when inner sleeve 4 presses down, spring 12 by compression, after inner sleeve push pedal 9 lost pressure, spring 12 recovered elasticity, active force is acted on the protruding circle 13, make inner sleeve 4 retractions return to original position.The location of this structure inner sleeve 4 mainly relies on protruding circle 13, also can establish the protruding circle 20 that a usefulness stationary fit mode cooperates in the inner sleeve end, but generally should consider linkage editor, in order to avoid dress does not advance spring.When inner sleeve 4 is subjected to upwards active force, it is force-closed to trocar sheath 3 to be delivered to pipe cap 10 repeated transmission by protruding circle 13, and when inner sleeve 4 is subjected to downward active force, protruding circle 13 is used masterpiece on the compression spring 12, the spring compression is delivered to protruding circle 14, protruding circle 14 is fixed on power formation sealing on the trocar sheath, so this structure also is reliable.

Fig. 5 is the peritoneoscope T pipe introducer concrete application clinically of this programme.Comprise liver 15 in the diagram, and the biliary common bile duct 16 of output, gallbladder 17, as this device be applied in utilize peritoneoscope to remove stone operation in the common bile duct after.Earlier want to cut on the common bile duct opening 18, after removing the interior calculus 19 of bile duct, by general operation convention, should insert the T pipe before sewing up opening 18, finish the pruning of T pipe this moment, the T pipe will be housed again and have the inserter front end of state shown in Figure 3 to stretch into the opening 18 from aperture that abdominal part is opened, the doctor presses down sleeve pipe with thumb, the inner sleeve lower end can be inserted the T pipe on arm and push in the common bile duct, and elasticity expansion fully in common bile duct that arm can rely on self is inserted in the both sides of doubling, finishes inserting the T pipe.

Because thereby the structure of this device produces useful effect, can be convenient under the peritoneoscope condition, safety, fast the T pipe is inserted common bile duct, thus produced good medical effect.
