Abstract

The utility model discloses a peritonrocentesis device for a transumbilical endoscopic surgery. The peritonrocentesis device comprises a hollow sheath tube, a ridge needle and a guide wire, wherein the hollow sheath tube consists of a left half sleeve and a right half sleeve which are identical to each other; the ridge needle is tightly sleeved in the sleeves in a sliding manner, and a guide wire channel arranged axially is arranged in the ridge needle. When the peritonrocentesis device is used, the guide wire penetrates in the ridge needle, and the ridge needle is inserted into the sheath tube. The guide wire passes through the umbilical region to enter the enterocoelia, then the ridge needle and the sheath tube outside the ridge needle are inserted into the enterocoelia together along the guide wire, subsequently, the guide wire is pulled out, the ridge needle is also pulled out, only the sheath tube is left, a soft endoscope passes through the sheath tube to enter the enterocoelia, and the sheath tube is torn and eradicated, so that the soft endoscope moves and is operated flexibly in the enterocoelia.

Description

A kind of abdominal paracentesis device through the soft endoscopic surgery of umbilicus

Technical field

This utility model relates to technical field of medical instruments, relates to a kind of abdominal paracentesis device through the soft endoscopic surgery of umbilicus particularly.

Background technology

Through umbilicus approach operation, be called again that (transumbilical endoscopic surgery TUES), is meant apparatus and peritoneoscope are inserted the technology that the abdominal cavity undergos surgery through the sleeve pipe of umbilical part through umbilicus approach scope or laparoscopic surgery.As a new technology, many authors describe with different terms, perform the operation like the single hole operation or through the umbilicus single hole.Advantage through the operation of umbilicus approach is better aesthetic and lighter operation wound.Because umbilical part is a natural gauffer position, almost can't see the operation vestige after the operation, has kept the integrity of stomach wall.Umbilical part is organized thinner relatively, and is lighter to injury of abdominal wall through the operating theater instruments of umbilical part.So that this technology has reached is more attractive in appearance, the effect of Wicresoft more.At present, through the soft endoscope of umbilicus (like gastroscope, intestinal mirror) operation, the most of puncture casing that adopts peritoneoscope (hard mirror, front end does not have bending section) of abdomen wall puncture pin.But sleeve pipe is inappropriate for the operation of soft endoscope.The peritoneoscope puncture casing blocks the bending section of soft endoscope distal end, cause soft endoscope can't free bend, change and get into the abdominal cavity direction.

The utility model content

The purpose of this utility model is to provide a kind of abdominal paracentesis device through the soft endoscopic surgery of umbilicus, to solve the problems referred to above that exist in the prior art.

The technical scheme that this utility model provides is following:

A kind of abdominal paracentesis device through the soft endoscopic surgery of umbilicus, it comprises:

The sheath pipe of one hollow, said sheath tube is made up of a left side half sleeve and right half sleeve that coincide mutually;

One rib pin closely is socketed in the said sleeve slidably, is provided with the silk guide passage of axial setting in the said rib pin, and

One seal wire.

In the preferred embodiment of this utility model, a left side half sleeve of said sheath pipe is provided with first tongue and groove, and right half sleeve is provided with second tongue and groove that cooperates with first tongue and groove.

In the preferred embodiment of this utility model, the horn-like end that said sheath pipe comprises a body and is positioned at body one end.It is smooth and easy that this horn-like end can make soft endoscope get into sheath Guan Shigeng.

In the preferred embodiment of this utility model, described rib needle tip is a prismatic.

During use, seal wire penetrates in the rib pin, and the rib pin inserts in the sheath pipe again.Earlier seal wire is got into the abdominal cavity through the umbilical part puncture, the rib pin inserts the abdominal cavity along seal wire together with its outer sheath pipe then.Subsequently, extract seal wire, the rib pin is extracted again, only stay the sheath pipe, soft endoscope gets into the abdominal cavity through the sheath pipe, and with the breaking into two with one's hands and pulling out of sheath pipe, soft like this endoscope is movable and operation is more flexible in the abdominal cavity.

The specific embodiment

Embodiment 1

The specific embodiment of this utility model, referring to figs. 1 through Fig. 3, and Fig. 5, a kind of abdominal paracentesis device through the soft endoscopic surgery of umbilicus comprises sheath pipe 1, rib pin 2 and seal wire 3.Wherein this seal wire 3 is elongated soft pin silk.

This rib pin 2 comprises an end 21 and a body 22; The diameter of its medial end portions 21 is greater than the diameter of body 22, and the other end of body 22 is tip 24, and it is that prismatic is so that pass umbilical part; Described prismatic i.e. this tip is that three faceted pebbles combine, and most advanced and sophisticated cross section is a triangle.Silk guide passage 23 connects body 22 and end 21 and most advanced and sophisticated 24 in the axial direction.

This sheath pipe 1 is a hollow form, axially is provided with the passage 15 of the body 22 that just holds rib pin 2.This sheath pipe 1 is made up of a symmetric left side half sleeve 11 and right half sleeve 12, forms body 13 and trumpet-shaped end 14 after the combination.

Referring to Fig. 5 to Figure 10, during use, seal wire 3 penetrates in the rib pin 2, and rib pin 2 inserts in the sheath pipe 1 again.Earlier seal wire 3 is got into abdominal cavity 4 (Fig. 5) through the umbilical part puncture, rib pin 2 and its outer sheath pipe 1 are together along seal wire 3 insertion abdominal cavities then, and sharp-pointed like this rib pin 2 successfully passes stomach wall, and can not damage intestinal tube (Fig. 6).Subsequently, extract seal wire 3 (Fig. 7); Rib pin 2 is extracted again, only stayed sheath pipe 1 (Fig. 8), soft endoscope 5 is through sheath pipe 1 entering abdominal cavity (Fig. 9); A left side half sleeve 11 and right half sleeve of sheath pipe 1 were opened and pulled out 1 in 12 minutes, and soft like this endoscope is movable and operation (Figure 10) more flexibly in the abdominal cavity.

Embodiment 2

Referring to Fig. 4, present embodiment and embodiment 1 are basic identical, and different is; In the present embodiment; A left side half sleeve 11 of sheath pipe 1 ' is provided with first tongue and groove 111, and right half sleeve 12 is provided with second tongue and groove 121 that cooperates with first tongue and groove 111, so that left half sleeve 11 is difficult for slippage with right half sleeve 12.

The above-mentioned specific embodiment that is merely this utility model, but the design concept of this utility model is not limited thereto allly utilizes this design that this utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading this utility model protection domain.
