Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to medical instruments, in particular to a surgical biopsy sampler. Background Art
[0002] Spinal vertebral lesions, especially spinal tumors, are a disease with a high incidence rate in the population; spinal tumors refer to primary or metastatic tumors and some tumor-like lesions that occur in the bones and their accessory tissues of the spine; spinal tumor treatment often requires biopsy to facilitate pathological diagnosis of the lesions and formulate a comprehensive plan. The spine has a complex structure, is deep in the body, and is adjacent to blood vessels, spinal cord, and peripheral nerves, so it is difficult to obtain pathological tissue for examination.
[0003] In the prior art, biopsies of spinal lesions are usually obtained by forceps or biopsy needle aspiration. Forceps require a larger incision, and forceps biopsy can obtain sufficient specimens, but it is traumatic and may cause cutting edge implantation and metastasis, seriously affecting the patient's prognosis. Biopsy needle aspiration is difficult to aspirate during the actual puncture biopsy process, and the specimen volume is small, which cannot meet the needs of pathological examination and is prone to cause a series of problems such as missed diagnosis and misdiagnosis.
[0004] The existing technical solutions have the following defects: the use of biopsy needles in surgery is complicated, which will increase the doctor's operation time, remove less tissue, and cannot meet the higher actual surgical sampling needs. Utility Model Content
[0005] The utility model provides a biopsy device required for tissue sampling during spinal vertebral disease surgery, and provides a spinal vertebral disease tissue biopsy device that is easy to operate and can remove more pathological tissue specimens, thereby reducing the difficulty of operation for doctors and increasing the sampling success rate.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A surgical biopsy sampler comprises a sampling tube, a sampling tube handle, a sampling outer tube and the sampling outer tube handle, wherein the sampling tube is a solid tube structure, one end of the sampling tube cooperates with the sampling tube handle, a sampling groove is arranged at the front part of the other end of the sampling tube, and the groove hole of the sampling groove is in a spiral ascending shape, the sampling groove of the spiral ascending groove hole is a spiral groove, and the spiral groove has a cutting edge, the sampling outer tube is a hollow circular tube structure, the sampling tube can be inserted into it and freely plugged in and pulled out, the rear end of the sampling outer tube cooperates with the sampling outer tube handle, and the front end head of the sampling outer tube is arranged to have a serrated structure.
[0008] As a further solution of the present invention: the length of the spiral groove is set to 10-30 mm.
[0009] As a further solution of the utility model: the outer wall of the sampling outer tube is engraved with scales, and the scales engraved on the outer wall can help doctors ensure the advancement depth.
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] The front end of the sampling needle designed in the utility model is a spiral groove structure. After the sampling needle reaches the specified position, the tissue can be taken out by rotating the handle. This design structure is simple to operate, and more pathological tissue specimens can be taken out, meeting higher actual surgical sampling needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.
[0018] See also Figure 1-4 A surgical biopsy sampler comprises a sampling tube 1, a sampling tube handle 2, a sampling outer tube 3 and a sampling outer tube handle 4.
[0019] like Figure 1 As shown: the sampling tube 1 is a solid tube structure, and one end of the sampling tube 1 is matched with the sampling tube handle 2.
[0020] like Figure 2 As shown: the front part of the other end of the sampling tube 1 is provided with a sampling groove, and the groove hole of the sampling groove is in a spiral ascending shape. The sampling groove of the spiral ascending groove hole is a spiral groove 5, and the spiral groove 5 has a cutting edge. The cutting edges of these spiral grooves 5 can effectively cut tissues during rotation, and can retain tissues in the spiral grooves 5 after rotation. The length of the spiral grooves 5 is set to 10-30mm, and the sampling outer tube 3 is a hollow circular tube structure (Note: it is a solid circular tube structure when matched with the sampling tube 1), and the sampling tube 1 can be inserted and freely plugged in and out.
[0021] like Figure 3 and Figure 4 As shown: the rear end of the sampling outer tube 3 cooperates with the sampling outer tube handle 4, and the front end head of the sampling outer tube 3 is configured to have a serrated structure. The serrated structure of the front end head design can help the sampling outer tube 3 to smoothly reach the designated position when it moves forward. The outer wall of the sampling outer tube 3 is engraved with scales, and the scales engraved on the outer wall can help doctors ensure the forward depth.
[0022] The working principle is: during actual operation, the doctor first determines the position during the operation, opens a channel at a suitable position away from the sampling position, and moves the sampler along the channel. The scale on the sampling outer tube 3 can be observed to control the distance of advancement. After moving the sampler to the precise position, the sampling tube handle 2 is turned. The required number of turns can be made according to the actual situation. The cutting edge of the spiral groove 5 at the head of the sampling tube 1 will cut the tissue and store it in the spiral groove 5. After the operation is completed, the sampler is taken out along the original channel and the tissue is taken out.
[0023] The front end of the sampling needle designed in the utility model is a spiral groove structure. After the sampling needle reaches the specified position, the tissue can be taken out by rotating the handle. This design structure is simple to operate, and more pathological tissue specimens can be taken out, meeting higher actual surgical sampling needs.
[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
[0025] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
