Problems solved by technology

[0003] In the existing cavity anastomosis device, the anastomotic ring is inserted into the cavity through a stapler in a minimally invasive way, and then the cavity that needs to be sutured is folded inward and fixed on the anastomotic ring, and the stapler is used to apply force The cavity is fixedly connected; in this way, an anastomotic ring is set inside, and a circle of scars will be produced in the wound during the healing process, which will gradually narrow the cavity and easily cause cavity blockage; It degrades in the subsequent process, but before it is completely degraded, it is prone to rejection, the patient needs to spend a long recovery period, and there is a great risk of sequelae

Embodiment 1

[0034] A cavity anastomosis device, comprising an anastomotic ring and a stapler, the anastomotic ring includes two anastomotic sub-rings, and the two anastomotic sub-rings are fitted with staples 1 and anastomotic holes 2; the anastomotic includes two movably connected anastomotics Both the sub-body and the stapler sub-body include an annular pliers head 3 with an opening and a pliers handle 4 connected with the annular pliers head 3, and the pliers handle 4 together constitute a hand-held device.

[0035] In the above-mentioned embodiment, during the operation, the two annular pliers 3 with openings respectively fix the two anastomotic rings, and extend the two anastomotic rings into the human body through the stapler to reach the affected area, and use the surgical Auxiliary to valgus and fix the two separated lumens on the staples 1 of the two anastomotic rings, and then trigger the stapler to snap the two anastomotic rings together; then insert the anastomotic rings and ri...

Embodiment 2

[0037] Embodiment 2 is basically similar to Embodiment 1, and its difference is:

[0038] combine figure 1 and figure 2 One of the anastomotic rings is provided with evenly distributed and staggered staples 1 and anastomotic holes 2 , and the other anastomotic ring is provided with corresponding anastomotic holes 2 and staples 1 .

[0039] In Example 2, the quality of the two anastomotic rings can be the same, avoiding the pressure from being biased to the horizontal side, and evenly distributing the rings so that the suturing effect of the cavity is better.

[0040] As a preferred embodiment, the shapes of the two anastomotic rings are both elliptical; compared to the circular shape, the ellipse can reduce the area of ​​body wounds and facilitate the insertion of the anastomotic rings into the body; The pressure in different directions (different from the above-mentioned horizontal pressure) makes the angle between the direction of the pressure and the direction of the exten...

Embodiment 3

[0045] Embodiment 3 is basically similar to Embodiment 1, and its difference is:

[0046] to combine image 3 , the stapler includes two mutually detachable and hinged stapler sub-body, the stapler sub-body includes two blades hinged to each other in the middle, the two blades at one end of the hinge point form an annular pliers head 3 with an opening, and the other end of the hinge point is two The hand-held device formed by the pliers handle 4 has a groove along the ring direction on the inner surface of the annular pliers head 3, and the width of the groove is not less than the thickness of the anastomotic sub-ring.

[0047] In Example 3, the structure of the stapler sub-body is similar to that of the traditional tweezers. The twisting of the two blades makes the two annular forceps heads 3 close together to fix the anastomotic ring. With the separation of the forceps handle 4, the two blades are separated, and then the anastomat ring is taken out from the opening of the a...

Abstract

The invention discloses a cavity anastomosis device, and relates to the field of medical instruments. The device has the advantages that the involution mode of an anastomotic stoma is optimized; suture materials are not left on the healed anastomotic stoma; and the risk of sequelae is reduced. According to the specific scheme, the device comprises an anastomosis ring and an anastomat body; the anastomosis ring comprises two anastomosis sub-rings; anastomosis nails and anastomosis holes are formed in the two anastomosis sub-rings in a matched mode; the anastomat body comprises two anastomat sub-bodies which are movably connected; each anastomat sub-body comprises an annular forceps head with an opening and a forceps handle connected with the annular forceps head; and the forceps handles jointly form a handheld device. According to the cavity anastomosis device, anastomosis with everted anastomotic stoma can be achieved, and the risk of sequelae is reduced; the anastomosis ring of the cavity anastomosis device is made of absorbable biological materials; suture materials are not left on the anastomotic stoma after healing; tissue foreign matter reaction is reduced; and the cavity anastomosis device has the advantages of being safer, lower operation cost, simple structure and good using effect.

Description

technical field [0001] The invention relates to the field of medical instruments, more specifically, it relates to a cavity anastomosis device. Background technique [0002] The anastomotic device is the first stapler in the world. It has been used for gastrointestinal anastomosis for nearly a century. It was not until 1978 that the tubular anastomotic device was widely used in gastrointestinal surgery. It is generally divided into one-time or multiple-use anastomotic devices, imported or domestic anastomotic devices. It is a device used in medicine to replace traditional manual suturing. Due to the development of modern technology and the improvement of manufacturing technology, the anastomosis device used in clinical practice is reliable in quality, easy to use, tight and suitable for tightness, especially its fast suturing, easy operation and There are few side effects and surgical complications, and it also enables tumor resection that was unresectable in the past.
