The product advantages of medical hollow drills are as follows:

1. Compared with the usual bone marrow puncture needle biopsy needle iliac bone puncture needle, medical hollow drills are used for extracting large amounts of bone marrow blood (50-200 milliliters), as well as for bone marrow injection infusion, cancellous bone injection, bone biopsy, and multi-purpose use. 2、 The structural design has a domestic monopoly patent, with 6 circular holes on the side wall that facilitate liquid entry and exit, an outer diameter of 2.6 millimeters, and a U-shaped hook pin front end that conforms to the doctor's usage habits. After blockage, the blockage can be removed. In addition, limiters prevent penetration during operation, control the depth of puncture, make operation easier, and achieve humanized design.

2. Medical hollow drills are mainly used for clinical GBR, which is to induce bone regeneration. While preparing the hole to increase the depth of the patient's autogenous bone fixation in the maxillary sinus, the autogenous bone from the patient's pit hole is taken. The depth of the bone extraction hole is equipped with an adjustable retaining ring, so the maximum amount of bone extraction can be freely adjusted according to one's own needs to save the amount of clinical bone powder used, which is the patient's autogenous bone.

3. Medical hollow drills are developed through continuous improvement of existing surgical tools. The traditional intervertebral foramen system method chooses the lumbar safety triangle. The lumbar safety triangle is a triangle composed of the lower edge of the exit root, the anterior edge of the articular process, and the upper edge of the pedicle, located at the exit of the intervertebral foramen. There are no important neurovascular structures within the triangle. Entering the intervertebral space through the safety triangle is the basis of traditional endoscopic approach for intervertebral foramen surgery. In some special cases, safe triangulation can be very difficult. For example, the variation of nerve roots at the exit of intervertebral foramen stenosis caused by intervertebral depression in the lumbar 5/sacral 1 space. Due to reasons such as high iliac crest, transverse process hypertrophy, and articular process hypertrophy, the safety triangle narrows, and surgical tools are prone to damage the nerve roots when entering.
