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] like 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 adopts a transition fit mode to cooperate with the rotating head 6, 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 with t...

Embodiment 2

[0029] like 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 Bucket 3a1 is a bucket-shaped structure, its open end is movably engaged with plug-in 3a5, and its connecting end is welded with rotating plate 3a2, and a stretching plate 3a4 is indirectly fitted between the rotating plates 3a2, and the weight pad 3a3 is embedded It is connected to the outer surface of the rotating plate 3a2, and the bottom of the expansion plate 3a4 is fixedly connected to the retaining ring 525. The gathering assembly 524 includes a sleeve cavity 4b1, a guide inclined plate 4b2, an adapter 4b3, a limit device 4b4, Leg 4b5, positioning frame 4b6, the socket cavity 4b1 is welded on the inner side of the bottom of the positioning frame 4b6, and the opening...

Abstract

The invention discloses a tumor excision device for the oncology department. The tumor excision device structurally comprises a cutter, a handle, a threaded cutter rod, a limiting rod, a sleeve and a rotating head. The cutter is fixedly connected with the threaded cutter rod through the handle; the threaded cutter rod and the limiting rod are inserted into the sleeve in a penetrating mode; the sleeve is matched with the rotating head in a transition fit mode; a clamping belt and a gathering assembly are arranged on a power assisting device; the clamping belt and the gathering assembly are matched on a protective ring; when the stress of the threaded cutter rod is increased, the threaded cutter rod can swing leftwards and rightwards in a barrel and extrude the protective ring to expand towards the two sides, so that the distance between the clamping belt and the threaded cutter rod is tensioned, the two sides of the gathering assembly are pushed to be opened downwards, and effective supporting is provided for the clamping belt; and the top of the clamping belt can prevent the threaded cutter rod from continuing to move, so that the anti-loosening function can be achieved.

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...
