Problems solved by technology

The core temperature of the renal parenchyma can be reduced to about 23 degrees Celsius by retrogradely perfusing ice water into the collecting system of the kidney. The influence cannot be ignored
Janetschek adopted the method of perfusing the renal artery with ice water for cooling protection, but it was not further promoted due to the complicated operation.
So far, there has not been an easy-to-use and highly operable device and method for maximally protecting the residual renal function in laparoscopic nephron-sparing surgery

Embodiment 1

[0046] As shown in the figure, the present invention provides a self-locking hemi-kidney tie, which consists of a kidney tie 1, a collar 2, a connecting rod handle 3, a collar card 4, a self-locking pull piece 5, and a self-locking slider. 6. The slider card 7 and the movable handle 8 are formed.

[0047] One end of the kidney tie 1 is a shaft ring 1.1, the other end has a tie hole 1.3, and there are several tie slots 1.2 on the kidney tie;

[0048] Ferrule 2, including ferrule shaft 2.1, strap channel 2.2 and ferrule card slot 2.3; the kidney strap is fixed on the ferrule shaft 2.1 through the shaft ring 1.1 to form a ring, and the end with the strap hole is inserted into the strap channel 2.2;

[0049] The connecting rod handle 3 includes a connecting rod and a fixed handle 3.3 at the rear end of the connecting rod. A self-locking tab groove 3.4 is provided in the hollow of the connecting rod. There is a slider chute 3.1 above;

[0050] The self-locking pull piece 5 is pl...

Embodiment 2

[0055] The rest are the same as in Example 1, the cable tie slots are 25 with a spacing of 2 mm, and the pull tab slots are 25 with a spacing of 2 mm;

[0056] The ferrule 2 also includes a positioning convex groove 2.4 for fixing the ferrule 2 and the connecting rod handle 3;

[0057] The hoop card 4 is composed of a card handle 4.1, a card hook 4.2 and a card shrapnel 4.3; the card hook 4.2 is inserted into the corresponding cable tie slot 1.2; the card handle 4.1 is embedded in the hoop card slot 2.3;

[0058] The slider card 7 has the same structure as the hoop card, and is also composed of a card handle, a card hook and a card shrapnel;

[0059] The connecting rod handle 3 also includes a handle shaft ring 3.2; the movable handle 8 also includes a handle shaft 8.3, and the handle shaft 8.3 is fixed to the handle shaft ring 3.2.

Embodiment 3

[0061] All the other are the same as in Example 1, the number of the cable tie slots is 35 with a spacing of 1.5mm;

[0062] There are 35 pull-tab slots with a spacing of 1.5mm;

[0063] The movable handle 8 also includes a handle stopper 8.2, which can prevent the instrument from falling when the doctor operates it.

Abstract

The invention belongs to the technical field of medical apparatuses and instruments, and provides a self-locking type half kidney loop ligature for a minimally invasive surgery. The self-locking type half kidney loop ligature for the minimally invasive surgery is formed by a kidney ligature (1), a hoop (2), a connecting rod handle (3), a hoop clamping sheet (4), a self-locking pull sheet (5), a self-locking sliding block (6), a sliding block clamping sheet (7) and a movable handle (8). According to the self-locking type half kidney loop ligature for the minimally invasive surgery, by means of controlling the kidney ligature (1), only the blood supply of the kidney of a tumor growth end can be cut off, the effect of tumor removal is guaranteed, blood loss volume in the surgery process is reduced, and most importantly, the ischemia time of reserved parts of the kidney is reduced to zero; the fact that blocking on the blood supply of the whole kidney is avoided, the functions of the reserved parts of the kidney are protected to the maximum extent, and the significance of nephron-sparing surgeries under a peritoneoscope is fully embodied.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a self-locking hemi-kidney band for maximally retaining residual kidney function in laparoscopic nephron-preserving surgery. Background technique [0002] With the gradual maturity of laparoscopic technology, laparoscopic nephron-sparing surgery techniques have been gradually mastered and applied by the majority of physicians, and its operation time, intraoperative blood loss and other indicators are gradually the same as those of open surgery, so laparoscopic nephron-sparing surgery Surgery has increasingly become the main means of minimally invasive surgical treatment of small renal cell carcinoma. However, because laparoscopic nephron-sparing surgery is difficult like traditional open surgery, after completely blocking the renal arterial and venous blood supply, the method of adding ice chips around the part of the kidney to be preserved is used to cool dow...
