Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a breast rotary cutting machine with a diversion function. Background Art

[0002] In traditional mastectomy, surgeons usually rely on palpation and visual guidance to locate and remove breast lesions. However, the complexity and diversity of breast tissue may lead to difficulties in locating and accurately removing lesions. The breast exciter with diversion function is designed to assist surgeons in making precise cuts and positioning in breast tissue to facilitate lesion localization and removal during surgery.

[0003] However, the following problems still exist in actual use:

[0004] (1) During excision surgery, a stable catheter position is crucial to maintaining stability and visibility of the surgical area. However, existing devices lack a guiding mechanism, which means that when inserting the catheter, it cannot be ensured that it is inserted vertically into the breast, resulting in the insertion position being offset, making it impossible to accurately locate the lesion or target area.

[0005] (2) The drainage tube is an important component in breast excision surgery and needs to be replaced according to the needs of the surgery. However, the drainage tube in the existing device is cumbersome and time-consuming to replace, and the sealing effect is easily deteriorated during replacement, thereby reducing the drainage effect.

[0006] For this purpose, the utility model introduces a breast rotary cutting machine with a diversion function. Utility Model Content

[0007] In view of the deficiencies in the prior art, the utility model provides a breast peeling machine with a diversion function, which has the advantages of preventing the insertion position from being offset and facilitating the replacement of the diversion tube, ensuring sealing, and solving the problems raised in the background technology.

[0008] The utility model provides the following technical solution: a breast peeling machine with a diversion function, comprising a carrying frame, a carrying plate is arranged inside the carrying frame, a peeling cutter is rotatably connected inside the carrying plate, a guiding mechanism is arranged inside the carrying frame, the guiding mechanism comprises a U-shaped block, a waist-shaped groove, a limiting rod, an oblique groove and a limiting groove, the surface of the U-shaped block is slidably connected to the inside of the carrying frame, the waist-shaped groove and the oblique groove are opened on the surface of the U-shaped block, the limiting groove is opened on the surface of the carrying frame, the surface of the limiting rod is slidably connected to the inside of the limiting groove and the oblique groove, one end of the limiting rod is fixedly connected to a side surface of the carrying plate, and the inside of the waist-shaped groove is slidably connected to the surface of the peeling cutter.

[0009] Preferably, an extension tube is fixedly connected to the bottom of the supporting plate, and the interior of the extension tube is rotatably connected to the surface of the rotary cutter. A sealing mechanism is provided at the bottom of the supporting plate, and the sealing mechanism includes a sealing ring, a guide tube, a drainage hose, a drainage hole and a mounting groove. The guide tube is sleeved on the surface of the rotary cutter, one end of the guide tube is sleeved on the surface of the extension tube, one end of the drainage hose is located inside the guide tube, the drainage hole is opened on the surface of the guide tube, the mounting groove is opened inside one end of the guide tube, the sealing ring is located inside the mounting groove, and the sealing ring is sleeved on the surface of the extension tube.

[0010] Preferably, a threaded rod is rotatably connected inside the carrying frame, and the surface of the threaded rod is threadably connected to the inner thread of the U-shaped block, so that the U-shaped block can be driven to move inside the carrying frame through the threaded rod.

[0011] Preferably, a driving motor is fixedly connected to one side surface of the carrying frame, and an output shaft of the driving motor is fixedly connected to one end of the threaded rod.

[0012] Preferably, a guide rod is fixedly connected to the interior of the bearing frame, and the surface of the guide rod is slidably connected to the interior of the U-shaped block. The guide rod can limit and guide the movement of the U-shaped block, making it more stable when moving.

[0013] Preferably, a cable tie is sleeved on one end surface of the flow guide tube.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. This breast peeling machine with diversion function is provided with a guiding mechanism. Starting the driving motor can drive the threaded rod to rotate, thereby driving the U-shaped block to slide inside the carrying frame. At this time, the guide rod plays a role of limiting and guiding the U-shaped block. When the U-shaped block moves, it will drive the limiting rods at both ends of the carrying plate to move inside the inclined groove, and the limiting rods will also move downward inside the limiting groove, thereby driving the carrying plate to move from top to bottom. The diversion tube can be inserted into the breast to reach the lesion point, and then the breast tissue can be removed by the rotation of the peeling knife. The setting of this structure helps to maintain the stability and accuracy of the diversion tube when it is inserted, prevents the insertion position from being offset, enables it to be accurately positioned at the lesion point, and helps the peeling knife to accurately remove breast tissue.

[0016] 2. This breast peeling machine with diversion function is provided with a sealing mechanism, and a sealing ring is placed inside the mounting groove. Then the diversion tube is passed through one end of the peeling knife and is put on the extension tube. Then, one end of the diversion tube is tightened with a cable tie. When the sealing ring is subjected to force, it will deform and block the gap between the diversion tube and the extension tube. When the peeling knife removes breast tissue, blood and tissue objects will be sucked into the inside of the diversion tube through one end of the diversion tube and the drainage hole, and discharged through the drainage hose. The setting of this structure can make it easier to replace the diversion tube and can provide better sealing, which helps to prevent liquid, gas or tissue objects from leaking from the gap between the diversion tube and the extension tube, ensuring that the liquid and tissue objects are effectively guided and discharged.
