Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an osteoporosis bone sampler. Background Art

[0002] Spinal compression fractures are common among the elderly, especially those with osteoporosis. Minimally invasive spinal surgery is becoming increasingly common as my country's aging population worsens. Determining the cause of vertebral fractures typically requires a pathological specimen, or bone sample.

[0003] Among them, an osteoporosis bone sample sampler with the announcement number CN219306783U includes a sampling sleeve, a memory metal part and a suction interface nut. The sampling sleeve has a first tubular cavity running through both ends thereof. The memory metal part includes memory metal claws, and at least two of the memory metal claws are arranged on the distal end of the sampling sleeve along the circumferential direction of the distal end of the sampling sleeve. Each of the memory metal claws can be in an open state at room temperature and in an inwardly retracted state at a temperature of 36°C and above. The suction interface nut is sleeved on the proximal end of the sampling sleeve and is threadedly connected to the sampling sleeve.

[0004] The above solution has the following shortcomings:

[0005] In the above technical solution, in order to prevent the memory metal claws from piercing other body tissues, the doctor needs to be very careful. If the doctor is not proficient in the sampling operation, it will take more time, which may cause the memory metal claws to close before reaching the designated position. Utility Model Content

[0006] In view of the above problems existing in the existing osteoporosis bone sample sampler, the present utility model is proposed.

[0007] Therefore, the purpose of the present invention is to provide an osteoporosis bone sample sampler, which solves the problem that the sampling operation takes more time when the doctor is not skilled, resulting in the memory metal claws closing before reaching the designated position.

[0008] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0009] An osteoporosis bone sample sampler includes a sampling rod, one end of which is connected to two semi-conical blocks, one side of each of the two semi-conical blocks is provided with a sampling groove, an elastic mechanism is provided between the two semi-conical blocks and the sampling rod, and a sleeve is slidably sleeved on the surface of the sampling rod, and the sleeve matches the two semi-conical blocks.

[0010] Preferably, the elastic mechanism includes two sliding rods, two connecting rods, two push blocks, two springs, two sliders and two hinge seats. The upper surfaces of the two semi-conical blocks are provided with grooves. The two sliding rods are respectively fixedly connected to the inside of the corresponding grooves. The two sliders are respectively slidably sleeved on the rod walls of the corresponding sliding rods. The two hinge seats are respectively fixedly connected to one side of the corresponding sliders. The two connecting rods are respectively fixedly connected to one side of the corresponding hinge seats. Two cavities are provided inside the sampling rod. One end of the two connecting rods passes through the lower surface of the sampling rod and extends to the inside of the corresponding cavities. The two push blocks are respectively fixedly connected to one end of the corresponding connecting rod. The two springs are respectively arranged inside the corresponding cavities and match the corresponding push blocks.

[0011] Preferably, the sampling rod and the ends of the two semi-conical blocks close to each other are each provided with a mounting groove, and a hinge is commonly provided inside the two corresponding mounting grooves, and the two semi-conical blocks are respectively hinged to one end of the sampling rod through the corresponding hinge.

[0012] Preferably, two placement grooves are provided at the lower end of the sampling rod, and the two hinged seats are matched with the corresponding placement grooves respectively.

[0013] Preferably, one end of the sampling rod is fixedly connected to a gripping rod, and one end of the gripping rod passes through one end of the sleeve and is fixedly connected to a stopper.

[0014] Preferably, both sides of the sampling rod are fixedly connected to limit bars, and the inner wall of the sleeve is symmetrically provided with two limit grooves, and the two limit grooves are matched with corresponding limit bars respectively.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] 1. The utility model completes the sampling work by inserting the sampling rod into the place to be sampled and then moving the sleeve, which then squeezes the two semi-conical blocks and makes them close to each other, and then the two sampling grooves are closed and the bone sample is stored therein.

[0017] 2. The utility model has an elastic mechanism. When the sampling work is completed, the sampling rod is taken out and then the mechanism sleeve is moved in the opposite direction. At this time, the rebound force of the two springs can be used to push the two push blocks apart respectively. Next, the two push blocks respectively drive the corresponding connecting rods to move and open the two semi-conical blocks, so that the sample can be taken out. BRIEF DESCRIPTION OF THE DRAWINGS
