Embodiment 1

[0034] Specific as Figure 1-6 As shown, the embodiment of the present invention is a compression hemostasis nail removal device, which includes a concave seat 1 and a nail cartridge assembly used in conjunction with it. The concave seat 1 is equipped with an annular nail abutment seat 102 with a nail abutment groove 101; The staple cartridge assembly includes a staple cartridge cover and a staple cartridge 202 installed in the staple cartridge cover, and staples 3 are installed in the staple cartridge 202 .

[0035] The structure of the staple 3 is as follows: Figure 6 As shown, it includes a connecting beam 301 and upwardly extending nail legs 302 connected to both sides of the connecting beam 301. The connecting beam 301 extends along one side of the width direction to form a reinforcing beam 303, and the surface of the reinforcing beam 303 is bent. With the addition of 303, the width of the connecting beam 301 of the flat nail is larger than that of the nail leg 302, and...

Embodiment 2

[0040] The embodiment of the present invention is a compression hemostasis nail removal device, specifically as Figure 6-9 As shown, the specific structure is the same as that of Embodiment 1, except that the annular nail abutment seat 102 is not provided with the first elastic body 103 covering the nail abutment groove 101, but is on the surface of the above-mentioned staple cartridge and facing the staples 3. A ring-shaped second elastic body 4 is provided at the position where the nails are pulled out. Several protrusions are provided on the bottom of the second elastic body 4. The second elastic body 4 is detachably connected to the staple cartridge through the protrusions.

[0041] The specific structure and connection relationship between the staple cartridge 202 and the second elastic body 4 are as follows: Figure 8-9 As shown, specifically, the outer surface of the staple cartridge 202 is provided with a number of limiting grooves corresponding to the positions and n...

Embodiment 3

[0043] The embodiment of the present invention is a compression hemostasis nail removal device, the specific structure is the same as that of embodiment 1, the difference is that on the basis of the structure of the embodiment, the use of a second elastic body is added, that is, on the surface of the above-mentioned nail cartridge, And facing the position where the staples 3 come out, there is also an annular second elastic body 4, the bottom of the second elastic body 4 is provided with a number of protrusions, and the second elastic body 4 is detachably connected to the staple cartridge through the protrusions , for the specific structure description of the staple cartridge 202 and the second elastic body 4, refer to the above-mentioned embodiment 2.

[0044] After the staple 3 is fired, it penetrates the second elastic body 4, the tissue to be anastomosed, and the first elastic body 103 in order to be formed, and the first elastic body 103 and the second elastic body 4 are s...

Abstract

The invention discloses a compression hemostasis depinning device and a peritomy anastomoses device adopting the same. The device comprises a concave base and a pin bin assembly. An annular pin abutting base with a pin abutting groove is installed on the concave base. The pin bin assembly comprises a pin bin sleeve and a pin bin installed inside the pin bin sleeve. An anastomose pin is installed inside the pin bin and comprises a connecting beam and pin legs connected to the two sides of the connecting beam to extend upwards, and the front edge of the connecting beam is fixedly provided with a strengthening beam extending forwards; an annular elastomer covering the pin abutting groove is arranged on the annular pin abutting base and / or an annular elastomer is arranged at the portion, right opposite to the pin outlet position of the anastomose pin, of the surface of the pin bin. By combining a flat pin and the elastomer, the problems of postoperation bleeding and hard depinning are well solved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a compression hemostasis and nail removal device and a circumcision stapler using the device. Background technique [0002] With the improvement of living standards, phimosis caused by prepuce, urinary infection, penile cancer and other diseases have attracted more and more attention. With the development of medicine and product research and development, more and more multifunctional medical devices are used in urology. Surgical clinical operations, circumcision stapler is one of them, the application of circumcision stapler has the advantages of less bleeding during surgery, shorter operation time, can reduce manual operation errors, avoid infection, fast postoperative functional recovery, etc. advantage. [0003] At present, the common circumcision staplers on the market use staples to suture the incision. However, when the existing staples compress the tis...
