背景技术Background technique
电切镜是一种广泛应用于泌尿外科手术中进行组织切除的器械，其主要应用场景包括经尿道前列腺电切术(TURP术)和经尿道膀胱肿瘤电切术(TURBT术)。在几十年的技术发展过程中，电切镜的结构基本已经固定，其一般包括内窥镜、内鞘、外鞘、操作器和手术电极。其中，操作器有主动和被动两种，标准配置为被动式，被动式使用时，手术电极前端在鞘套内，医生手握操作器把手使操作器上的滑块进行往复运动，操作器包括两个手柄，手术时，医生推动手柄，带动手柄上的电极随滑块做往复运动，以实现切割。The resectoscope is an instrument widely used for tissue resection in urological surgeries.

When using the passive type, the front end of the surgical electrode is in the sheath, and the doctor holds the handle of the manipulator to make the slider on the manipulator reciprocate. The manipulator includes two Handle, during surgery, the doctor pushes the handle to drive the electrodes on the handle to reciprocate with the slider to achieve cutting.
然而，一般的TURP术或TURBT术手术时间较长，在半个小时到两三个小时之间不等，在这期间，医生的手指和手臂需要不停地动作以切除目标组织，并且医生需要对手柄施加较大的力，导致医生手部很容易疲劳，从而可能出现手术动作不标准的情况，影响手术的安全性（例如，影响伤口的切除范围、止血效果等）。However, the general TURP or TURBT surgery takes a long time, ranging from half an hour to two or three hours. During this period, the doctor's fingers and arms need to keep moving to remove the target tissue, and the doctor needs to Applying a large force to the handle will cause the doctor's hands to easily fatigue, which may lead to non-standard surgical movements and affect the safety of the operation (for example, affecting the range of wound resection, hemostatic effect, etc.).
因此，我们推出一种电动电切镜。Therefore, we introduced an electric resectoscope.

The external host controls the drive motor 13 connected to it through the cable to rotate forward. The drive motor 13 is based on The tooth box 14 drives the driving screw 15 to rotate, and the driving crescent pin 165 slides along the reciprocating thread of the driving screw 15, thereby using the electrode holder 16 to drive the surgical electrode 3 from the initial position (the initial position is on the driving screw 15 close to the driven gear 142) moves distally. After reaching the distal extreme position, due to the structural characteristics of the driving screw 15, the surgical electrode 3 can automatically move in the opposite direction and return to the initial position. This cycle continues to drive the surgical electrode. 3 performs reciprocating motion back and forth to remove the diseased tissue; during this process, for example, when the surgical electrode 3 is moving distally, when the doctor needs to perform a hemostasis operation on a certain part, the surgical electrode 3 can reach the When the target site is targeted, release the forward button 17. At this time, the drive motor 13 stops rotating forward, and the surgical electrode 3 stops at the target site. The doctor can perform a hemostasis operation. After that, according to actual needs, he can choose to continue pressing the forward button 17 to perform the operation. The electrode 3 continues to move forward to the distal extreme position to continue the reciprocating motion, or you can choose to continue pressing the reverse button 18 to reverse the driving motor 13 and control the surgical electrode 3 to move backward to the initial position to continue the reciprocating motion for resection. diseased tissue.
此外，当医生需要切除某个特定部位时，可通过正向按键17和反向按键18的交替使用来实现。具体来讲，在切除该特定部位时，医生按住正向按键17，驱动电机13正转，控制手术电极3向前运动至该特定部位，松开正向按键17，按住反向按键18，驱动电机13反转，控制手术电极3向后运动，实现对该特定部位的一次切割，可重复该操作过程，直到完全切除该特定部位，避免了医生在长时间的手术期间内，手指和手臂需要不停地动作以切除目标组织，并且需要对手柄施加较大的力，导致手部很容易疲劳，从而可能出现手术动作不标准的情况，避免影响手术的安全性（例如，影响伤口的切除范围、止血效果等），提高医生手术操作的精准性，高效实用。In addition, when the doctor needs to remove a specific part, this can be achieved by using the forward button 17 and the reverse button 18 alternately. Specifically, when resecting the specific part, the doctor presses the forward button 17, drives the motor 13 to rotate forward, controls the surgical electrode 3 to move forward to the specific part, releases the forward button 17, and presses the reverse button 18. , the motor 13 is driven to reverse, and the surgical electrode 3 is controlled to move backward to achieve one cutting of the specific part. The operation process can be repeated until the specific part is completely removed, which avoids the doctor's fingers and fingers during the long operation. The arm needs to move continuously to remove the target tissue, and a large force needs to be exerted on the handle, causing the hand to easily fatigue, which may lead to non-standard surgical movements and avoid affecting the safety of the operation (for example, affecting the wound). Excision range, hemostatic effect, etc.), improve the accuracy of doctors' surgical operations, and are efficient and practical.
