Description

Technical Field

[0001] This utility model relates to a laser operating handle, and more particularly to a split-type laparoscopic laser operating handle. Background Technology

[0002] With advancements in imaging technology, the detection rate of small-volume renal lesions (maximum diameter less than 4 cm) continues to rise, accounting for 66% of all newly diagnosed renal tumors. To adapt to these changes, the number of laparoscopic radical nephrectomy surgeries is gradually decreasing; laparoscopic partial nephrectomy, due to its preservation of normal nephrons in the affected kidney while ensuring the effectiveness of tumor treatment, is gaining increasing recommendations.

[0003] In conventional partial nephrectomy, the renal artery blood supply needs to be temporarily blocked, and then restored after tumor removal and wound closure. Closure of the renal artery inevitably leads to renal ischemia and hypoxia, and reopening the vessel causes ischemia-reperfusion injury, potentially resulting in decreased renal function. Since the degree of renal injury is directly proportional to the duration of warm ischemia, reducing ischemia time can improve renal function after laparoscopic partial nephrectomy. Furthermore, after tumor removal, the renal wound needs to be sutured, which can cause secondary damage to the kidney, prolong the operation time, and even lead to rebleeding at the suture site. Therefore, discovering a laparoscopic partial nephrectomy technique that reduces or eliminates the need for renal artery closure and wound closure is a current emerging research direction.

[0004] Laser technology has been applied to a variety of medical treatments, including tissue resection using lasers as tools. Lasers have excellent cutting and tissue coagulation effects and can be emitted continuously, making them an excellent tool for laparoscopic partial nephrectomy. In 2002, Lotan et al. reported three cases of partial nephrectomy without blocking the renal artery using holmium lasers, and all surgeries were successfully completed. In 2013, Sciarra et al. reported 10 cases of partial nephrectomy using thulium lasers, including 3 cases of laparoscopic partial nephrectomy (complete blocking of the renal artery) and 7 cases of open partial nephrectomy (without blocking the renal artery). The average tumor size was 4 cm, and there were no postoperative complications. Pathology showed that the capsule was intact [8]. Domestic studies by Wang Hang et al. reported the use of a laser in laparoscopic partial nephrectomy with zero ischemia in 24 patients with T1N0M0 stage exoprotruding renal tumors. The average tumor size was 19 mm, the operation time was 50-100 minutes, and the blood loss was 10-200 ml. No serious postoperative complications occurred, and follow-up renal function tests showed little change compared to preoperative levels. All tumor margins were negative. They concluded that laser partial nephrectomy is safe and feasible for renal tumors meeting the criteria, and it has a good effect on preserving renal function. Duan Na et al. reported that partial nephrectomy without blocking the renal pedicle is safe and effective, reducing renal warm ischemia time and promoting postoperative recovery. Dong Jie et al. used a 980 / 1470 nm bipolar laser for partial nephrectomy, including 25 cases, of which 23 achieved zero ischemia laparoscopic partial nephrectomy with satisfactory postoperative results. In summary, lasers have great application potential in partial nephrectomy, optimizing the surgical procedure for renal tumors, maximizing the protection of renal function, and shortening operation time.

[0005] During laser surgery, optical fibers of varying diameters are used as "surgical tools." However, in most hospitals, the fiber insertion device is a patchwork of catheters and suction devices. Laser surgery generates a large amount of smoke and heat, necessitating continuous saline irrigation and intermittent fluid aspiration to remove the smoke and heat. Currently, a well-designed laparoscopic laser operating handle is not yet available, which limits the widespread adoption of laser surgery.

[0006] Patent CN201721813643.3 provides a laser handpiece, comprising: a handle body with a hollow cavity, a tensioning mechanism, a smoke extraction tube, and a flexible tensioning member disposed within the cavity; the handle body includes a straight portion and a bendable curved portion, the curved portion including a free end and a fixed end connected to the straight portion; a sliding mechanism is disposed on the surface of the straight portion along its length direction, the smoke extraction tube is detachably disposed on the sliding mechanism and can slide along the length direction of the straight portion; the tensioning mechanism is disposed on the straight portion and can move relative to the straight portion to a first tensioning position and a second tensioning position; a first end of the tensioning member is connected to the tensioning mechanism, and a second end of the tensioning member is disposed on the curved portion near the free end. This embodiment allows the laser handpiece to have different bending angles, making it more flexible and convenient to use; it also allows for the removal of smoke during laser surgery through the laser handpiece, eliminating the need for additional smoke extraction mechanisms and reducing the trauma of laser surgery. In patent CN201721813643.3, the laser handpiece has different bending angles. Different bending angles are achieved by stretching the free end with a tensioning member, so that the free end forms a bending angle relative to the fixed end. At the same time, the reset structure can be a spring set in the cavity of the bending part 120, or a flexible body set in the cavity of the bending part 120. When the bending part 120 is formed by winding a flexible metal wire, the bending part 120 also has a reset structure, realizing different bends and simultaneously removing smoke during laser surgery. However, the fiber optic tube is not set outside the main body of the handpiece and runs parallel to it. The end of the fiber optic sleeve cannot achieve three bend angles. Additional control is required through other structures such as a tensioning structure, which makes the structure more complex and cannot simultaneously connect to flushing or negative pressure suction.
