Description

Laparoscopic sheath clamp and puncture needle

Technical Field

The utility model relates to a medical surgical instrument, in particular to a single-hole laparoscope sheath clamp with smaller abdominal wall wound and more convenient use.

Background

With the vigorous development of minimally invasive surgical techniques, laparoscopy has become an important treatment for surgery, and single-port laparoscopy has gradually come into the field of vision as a new concept and new technology in recent years.

The surgical procedure of the single port laparoscopic surgical technique is substantially identical to that of the conventional laparoscopic surgery, but the laparoscope and various instruments are almost parallel to the abdominal cavity in the single port condition, which makes the operation difficult. The difficulty is that the operation is easy in both minimal invasion and operation.

The traditional single-port laparoscope sheath clamp needs a larger navel incision, and the peritoneum must be lifted to be plugged into the single-port laparoscope sheath clamp, so that the advantage of more minimally invasive performance of the single-port laparoscope is difficult to embody. However, the convenience of minimally invasive and surgical procedures has always been incompatible.

Further: the rubber ring is provided with a suture thread passing through the through hole.

Preferably: the number of the operation clamp channels 1 is 4.

Preferably: the number of the cuts is 5.

Preferably: the diameter of the integral portion tapers away from the snap-fit engagement.

A retrograde knife edge is arranged at one end, far away from a buckle connection part, of the puncture needle, and the retrograde knife edges correspond to incisions one by one.

Compared with the prior art, the utility model, following beneficial effect has:

the utility model discloses can reduce the stomach wall incision as far as possible in order to satisfy the wicresoft that the patient required, can compromise the convenience that the operator operated simultaneously again, solve the problem of instrument insert abdominal cavity back operation difficulty.

Detailed Description

The invention will be further elucidated with reference to the drawings and specific embodiments, it being understood that these examples are intended to illustrate the invention only and are not intended to limit the scope of the invention, and that modifications to the various equivalent forms of the invention, which may occur to those skilled in the art after reading the present invention, fall within the scope of the invention as defined in the claims appended hereto.

A laparoscopic sheath clamp, as shown in fig. 1-4, comprises an operating forceps channel 1, an external balloon 2, an air inlet and outlet valve 3, an external balloon buckle 4, a puncture needle operating end 6, a buckle joint part 7, a rubber ring 8 and a sheath tube, wherein:

the operation clamp channel 1 and the air inlet and outlet valve 3 are arranged on the outer balloon 2, and the outer balloon 2 is provided with a buckle 4; the operating forceps channels 1 are channels for accessing the laparoscopic operating forceps, and the number of the operating forceps channels 1 is 4.

The puncture needle operating end 6 is arranged on the buckle joint part 7, and the outer balloon 2 is fixedly connected with the inside of the sheath clamp through the matching of the buckle 4 and the buckle joint part 7;

the sheath tube comprises an outer sheath tube and an inner sheath tube, the inner sheath tube is a section entering the abdominal cavity, the inner sheath tube is made of a hose, the sheath tube is arranged below the buckle joint part 7, and the rubber ring 8 is arranged on the buckle joint part 7; the rubber ring 8 is provided with a suture line passing through hole 81. Reserve a plurality of through-holes 81 on 8 through the rubber circle, prevent that the sheath card from extracting in the operation process, during the use, the stylolite can pass through-hole 81 and directly sew on skin, and the solution is the fixed sheath card problem of not extracting.

The hose 9 is divided into a cut-away part 91 and a complete part 92, the cut-away part 91 is positioned at one side close to the snap joint part 7, more than one notch 911 is axially arranged on the cut-away part, and the number of the notches 911 is 5. Whereas the full portion 92 is located on the side away from the snap engagement 7, the diameter of the full portion 92 gradually decreases in the direction away from the snap engagement 7. That is to say, the hose entering the abdominal cavity is designed into an imaging indwelling needle-like hose, the proximal end of the hose is longitudinally split into five parts in advance, the distal end of the hose is circular and complete, a small point at the distal end of the indwelling needle is beneficial to puncture, and the design is the same, and the distal end is small.

A retrograde knife edge is arranged at one end, far away from a buckle connection part 7, of the puncture needle and corresponds to a notch 911 one by one. The blade direction is in line with the pre-split slit 911 of the hose.

The distal end of the puncture needle is provided with a retrograde knife edge which is in the same line with the pre-dissection line (incision 911) of the hose 9. When the sheath card enters the abdominal cavity to pull out the puncture needle 10, the reverse blade of the puncture needle can cut open the distal part of the hose, and the hose can be completely cut open, so that the problem that the operating forceps can not be opened can be well solved.

When the puncture needle is pulled out after the sheath clip enters the abdominal cavity, the retrograde blade of the puncture needle can cut open the whole part 92 of the hose, and the hose can be completely cut open. The sheath clamp device has a simple structure, and can ensure that the instrument has enough operation space while minimizing the incision of the abdominal wall.

The inner diameter of the improved single-hole laparoscope sheath clamp of the utility model can pass through the light source and the operating forceps. In order to ensure that the instrument can be swung open and operated in space after being inserted, an abdominal cavity entering section similar to a common sheath clamp is needed, so the abdominal cavity entering section is designed into an indwelling needle-like hose, the proximal end of the hose is longitudinally split into five parts in advance, and the distal end of the hose is complete in a circular shape. For convenient puncture, the distal end has a small diameter and is attached with a retrograde blade, and the retrograde blade and the hose pre-dissection line are on the same straight line. When the sheath clamp enters the abdominal cavity to pull out the puncture needle, the retrograde blade of the puncture needle can cut the distal part of the hose open, the hose can be completely cut open, and the problem that the operating forceps can not be opened can be well solved.

The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
