Problems solved by technology

[0003] When the cutting force applied by the cutter on the tumor resection site increases, the force on the threaded cutter rod will also increase. When the corresponding force is reached, it will drive its own threaded rod to loosen and rotate in the sleeve, so that the cutter will Offset its original cutting trajectory, causing damage to other parts, reducing the accuracy of the cutting knife, but also increasing the difficulty of the doctor's operation and affecting the progress of the operation

Embodiment 1

[0027] Such as Figure 1-Figure 3 As shown, the present invention provides a tumor resectator for oncology, its structure includes a cutting knife 1, a handle 2, a threaded knife rod 3, a limiting rod 4, a sleeve 5, a rotating head 6, and the cutting knife 1 passes through the handle 2 It is fixedly connected with the threaded knife rod 3, the threaded knife rod 3 and the limiting rod 4 are inserted inside the sleeve 5, the sleeve 5 cooperates with the rotating head 6 through the threaded knife rod 3, and the sleeve 5 includes a buckle 51. Power booster 52, composite plate 53, cylinder body 54, and partition 55. The outer surface of the buckle 51 is welded and connected with a partition 55. Both sides of the partition 55 are scarfed and connected with composite panels 53. The composite The two sides of the plate 53 are sleeved on the inner wall of the cylinder 54, and the top of the cylinder 54 is equipped with a booster device 52. The booster device 52 indirectly cooperates w...

Embodiment 2

[0029] Such as Figure 4-Figure 6 As shown, on the basis of Embodiment 1, the present invention combines the mutual cooperation of the following structural components. The entrainment belt 523 includes a buckle bucket 3a1, a rotary plate 3a2, a weight pad 3a3, a spreader plate 3a4, and an insert 3a5. The buckle The bucket 3a1 is a bucket-shaped structure, its open end is movably engaged with an insert 3a5, and its connecting end is welded with a rotating plate 3a2, two rotating plates 3a2 are provided, and a spreading plate 3a4 is provided on the rotating plate 3a2, The weight pad 3a3 is embedded and connected to the outer surface of the rotary plate 3a2, the bottom of the expansion plate 3a4 is fixedly connected to the retaining ring 525, and the folding assembly 524 includes a socket cavity 4b1, a guide slant plate 4b2, a transfer Part 4b3, limit device 4b4, leg 4b5, positioning frame 4b6, the socket cavity 4b1 is welded and connected to the inner side of the bottom of the p...

Abstract

The invention discloses a tumor resecting device used in oncology, the structure of which comprises a cutting knife, a handle, a threaded knife rod, a limiting rod, a sleeve, and a rotating head. The rod is inserted inside the sleeve, and the sleeve adopts a transition fit method to cooperate with the rotating head. An entrainment and shirring component is provided on the booster device, and the entrainment and shirring component is used to cooperate on the retaining ring. When the force on the threaded cutter rod increases , it will swing left and right in the barrel, and the extrusion retaining ring will expand to both sides, which will not only tighten the distance between the entrainment and the threaded knife rod, but also push the sides of the gathering component to open downwards, effectively supporting the entrainment, so that the entrainment The top will prevent the threaded tool rod from continuing to move, which can realize the anti-loosening function.

Description

technical field [0001] The invention relates to the field of oncology medical equipment, in particular to a tumor resecting device for oncology. Background technique [0002] Tumor refers to the neoplasm formed by the proliferation of local histiocytes under the action of various tumorigenic factors, because this neoplasm is mostly in the form of space-occupying blocky protrusions, also known as neoplasms. In tumor surgery, it is usually necessary to treat Only by resecting the tumor tissue can a radical cure be achieved. The existing oncology tumor resectectomy device is prone to the following disadvantages during use: [0003] When the cutting force applied by the cutter on the tumor resection site increases, the force on the threaded cutter rod will also increase. When the corresponding force is reached, it will drive its own threaded rod to loosen and rotate in the sleeve, so that the cutter will Deviation of its original cutting trajectory will cause damage to other pa...
