Description

Technical Field

[0001] The utility model relates to the technical field of medical assistance, in particular to a bladder and urethra anastomosis pinhole forceps for laparoscopic radical prostatectomy. Background Art

[0002] In my country, radical prostatectomy is the standard procedure for the treatment of early prostate cancer. The key and difficulty of the operation lies in the reconstruction of the lower urinary tract, that is, the key technical issue of bladder-urethra anastomosis.

[0003] At present, the method of suturing with a needle holder and a separation forceps is mostly used. The surgeon uses the separation forceps in the left hand and the needle holder in the right hand to anastomose the bladder opening and the urethral stump under laparoscopy. At least 8 stitches are required. The following defects exist when suturing the urethral stump: first, it is difficult to determine the needle insertion margin and it is unbalanced; second, the needle insertion and needle withdrawal directions are inconsistent, and the direction difference is very large, resulting in loose anastomosis. Some patients have postoperative urine leakage; third, the difficult operation leads to a long operation time and increased intraoperative risks. Therefore, the present device provides a needle hole forceps for bladder and urethral anastomosis in laparoscopic radical prostatectomy. Utility Model Content

[0004] The embodiment of the utility model provides a laparoscopic radical prostatectomy bladder urethra anastomosis pinhole forceps to solve the above-mentioned technical problems.

[0005] The embodiment of the utility model adopts the following technical scheme: comprising a suture needle and a suture body for suturing and puncturing a wound required by a patient, a first needle holder for clamping the suture needle in and out of the wound required by the patient, and a second needle holder for clamping and limiting the suture needle, wherein the first needle holder is clamped at the head of the suture needle, and the second needle holder is clamped at the middle of the suture needle to limit the position of the suture needle, the suture needle is connected to the suture body, and the suture needle is a round needle;

[0006] When the medical staff of this device sews up the anastomotic wound between the bladder opening and the urethral stump of the patient, they can first insert the second needle holder into the urethra by the operator's left hand, and make the needle enter the limiting position from the second needle holder to complete the limiting position or limit the position by clamping, so as to stabilize the suturing needle. At this time, the first needle holder in the operator's right hand can clamp the suturing needle to advance the suturing needle, thus ensuring the consistency of the needle insertion and needle withdrawal directions, and the sutured anastomosis is relatively tight. At the same time, the operator's left hand holding the second needle holder can assist in entering the depth of the urethra, so as to control the stability and consistency of the needle margin, thereby improving the treatment effect.

[0007] Furthermore, the two clamping end tips of the front end of the first needle holder are both arc-shaped, and the inner sides of the handle of the first needle holder are provided with matching three-step lock buckles, and the inner sides of the handle of the first needle holder and the handle of the second needle holder are both provided with matching three-step lock buckles;

[0008] The two clamping end tips at the front end of the first needle holder are both arc-shaped, so that when the operator holds the first needle holder in his right hand to perform treatment, the patient will not be stabbed or injured. The inner sides of the handle of the first needle holder are provided with matching three-stage locks, so that the operator can clamp and lock the suture needle according to the treatment operation steps to perform suture and traction, thereby improving the treatment effect.

[0009] Furthermore, one of the two clamping ends at the front end of the second needle holder is provided with a needle clamp hole groove, and the needle clamp hole groove is in a matching state with the suture needle.

[0010] A needle clamp hole groove is provided on one of the two clamping ends at the front end of the second needle holder, and the needle clamp hole groove is in a compatible state with the suture needle, so that after the suture needle passes through the needle clamp hole groove and is limited by the needle clamp hole groove, it avoids the inconsistency of needle insertion and needle exit directions and margin offset, which causes the direction of the needle tip to deviate far from the original direction and causes serious misalignment during suturing.

[0011] Furthermore, the two clamping end tips at the front end of the second needle holder are both blunt-shaped;

[0012] The two clamping end tips at the front end of the second needle holder are both blunt-shaped, so that when the operator holds the second needle holder with his left hand to perform treatment, the patient will not be stabbed or caused harm to the patient. In addition, when the operator holds the second needle holder with his left hand to open the suturing field, the patient will not be stabbed or caused harm to the patient. This is more conducive to opening the suturing field and providing treatment assistance to the operator.

[0013] Furthermore, the handle of the first needle holder and the handle of the second needle holder are both made of reflective material;

[0014] Since the handle of the first needle holder and the handle of the second needle holder are both made of reflective material, when the operator is performing treatment, the reflection of the first needle holder handle and the second needle holder handle will not cause the operator's hands to suddenly pause or shake, causing the suture position to be incorrectly shifted, thereby reducing the risk of treatment.

[0015] At least one of the above technical solutions adopted in the embodiment of the utility model can achieve the following beneficial effects:

[0016] When the medical staff of the device sutures the wound of the anastomotic bladder opening and the urethral stump of the patient, the operator can first insert the second needle holder into the urethra by holding it with the left hand of the operator, and make the needle enter the limit position from the limit position of the second needle holder to complete the limit position or limit it by clamping, so as to stabilize the suture needle. At this time, the first needle holder in the right hand of the operator can clamp the suture needle to advance the suture needle, thus ensuring the consistency of the needle insertion and needle withdrawal directions, and the sutured anastomosis is relatively tight. At the same time, the operator can hold the second needle holder in the left hand to assist in entering the urethra, so as to control the stability and consistency of the needle margin, thereby improving the treatment effect.

[0017] A needle clamp hole groove is provided on one of the two clamping ends at the front end of the second needle holder, and the needle clamp hole groove is in a compatible state with the suture needle, so that after the suture needle passes through the needle clamp hole groove and is limited by the needle clamp hole groove, it avoids the inconsistency of needle insertion and needle exit directions and margin offset, which causes the direction of the needle tip to deviate far from the original direction and causes serious misalignment during suturing.
