Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to an auxiliary handle. Background Technology

[0002] In urology, endoscopic lithotripsy is commonly used to remove stones from patients, resulting in less pain, fewer postoperative complications, and faster recovery.

[0003] Disposable urinary stone occlusion catheters (hereinafter referred to as occlusion catheters) can be used to block stones in the upper and middle ureter during lithotripsy to prevent stone fragments from drifting into the renal calyces. In addition, they can also drag stone fragments into the bladder to achieve the function of stone removal. In percutaneous nephrolithotomy, occlusion catheters can also be used to block stones at the ureteropelvic junction before lithotripsy.

[0004] In clinical use, the mandrel of the occlusion catheter needs to be advanced. A guidewire lock is commonly used as a handle to lock the mandrel for easy advancement. The outer tube is usually wrapped in medical gauze for gripping. When the occlusion catheter retracts, advancing the mandrel again can be difficult because the mandrel is prone to bending, making it impossible to unfold the catheter. In this case, it is necessary to manually pinch the tip of the mandrel and slowly advance it, reducing surgical efficiency. Traditionally used guidewire locks only assist in the operation when the occlusion catheter retracts, but they do not assist in the operation when unfolding the occlusion catheter.

[0021] like Figure 1 As shown, a specific embodiment of this application includes: an outer tube auxiliary handle 2A and a spindle auxiliary handle 2B. The outer tube auxiliary handle 2A is composed of a left clamping wall 20, a right clamping wall 21 and an outer tube sleeve shaft 22, and the spindle auxiliary handle 2B is composed of a left clamping wall 20, a right clamping wall 21 and a sliding sleeve shaft 23.

[0022] An application scenario of one embodiment of this application is as follows: Figure 2 As shown, the occlusion catheter pushing component consists of an outer tube 1 and a mandrel 3, with the mandrel 3 set inside the outer tube 1, allowing them to slide relative to each other. The outer tube sleeve 22 in the outer tube auxiliary handle 2A is adapted to the diameter of the sliding sleeve 23 in the mandrel auxiliary handle 2B. The outer tube auxiliary handle 2A is inserted into the outer tube 1, the mandrel auxiliary handle 2B is inserted into the mandrel 3, and the sliding sleeve 23 is inserted into the outer tube sleeve 22. Pressing the left clamping wall 20 and the right clamping wall 21 can clamp the outer tube 1 and the mandrel 3. The occlusion catheter unfolds and retracts as follows: one hand presses the outer tube auxiliary handle 2A on the outer tube 1 and keeps it stationary, while the other hand presses the mandrel auxiliary handle 2B on the mandrel 3 and pushes it forward to unfold the occlusion catheter. Pressing the mandrel auxiliary handle 2B and pulling it backward can retract the occlusion catheter.
