[ background ] A method for producing a semiconductor device
The laser scalpel is used as a treatment mode for replacing a traditional metal knife and a high-frequency electrotome, and becomes the most safe, efficient and low-damage operation method at the present stage. Drilling is a common means of laser medical processing at the present stage, and efficient, safe and low-damage straight hole processing can be realized by utilizing the collimation characteristic of laser. However, for the complex environment in the human body, in some situations, special curved hole processing is required for the patient to achieve the purpose of treatment and repair.
The suture anchoring technology is a standard technology for clinically performing tissue repair suture at present, and the conventional operation is to implant an anchor on bone tissue, realize anchoring in the bone tissue through a thread, a barb or a wing-shaped structure and then perform tissue repair suture by utilizing a suture pre-penetrated through an anchor tail hole. However, no matter how the material is improved, the anchor is always foreign to the human body, the size of the anchor has certain occupation effect, and the risk of operation failure caused by insufficient holding force of the anchor and even extraction from bone tissue exists, especially for the elderly patients with osteoporosis. In a few clinical emergency situations, when a doctor needs to perform tissue repair suture temporarily in an operation without preparing an anchor or the anchor cannot be applied due to cost and other reasons or the anchor suture fails or even the anchor is pulled out in the operation, the emergency treatment method comprises the steps of drilling straight holes in a bone section, passing through holes by using needles and lines, anchoring by using a bone beam between the holes and then performing tissue suture repair. However, bones are often in a cambered surface (bone end) or a cylindrical surface (diaphysis), so that the opening of a straight hole and the bone surface form an acute angle, so-called 'turning killer' effect can be generated to cut the suture, and the suture is clinically only a temporary substitute measure and cannot be used for tissue repair suture conventionally. If an arc-shaped bent hole can be drilled on a bone, the wall of the hole is polished, and then a suture is penetrated into the hole channel, so that the suture and the hole opening are not in an acute angle relationship, the suture cannot be cut due to the turning killer effect, the effect of an anchor can be replaced, the bone beam between the inlet and the outlet of the hole channel is directly utilized to realize anchoring, and then the suture is carried out by the suture.
However, the existing laser drilling device for medical treatment mainly drills straight holes, such as the laser bone drilling device with patent application publication No. CN111053611A, and the implementation scheme is as follows: the laser orthopaedics drilling device comprises an optical fiber which is arranged on a fixing piece and connected with a laser, wherein a stepping motor is arranged on the fixing piece, and the stepping motor is in movable fit connection with a handle through a screw rod nut pair. The problem of its solution still limits to the drilling straight hole, and the angle of front end drilling can't be adjusted, only can improve the degree of depth of drilling, and its drawback is, to the operation that needs carry out curved bore processing, still can't apply the solution, and the limitation is stronger.

The same may be used for subsequent tissue repair suturing procedures.
Furthermore, the optical fiber bullet realizes the turning of the optical fiber bullet by adding a memory metal outer casing, a rigid metal sleeve, end face treatment, oblique light output and the like. The low-loss transmission of the fiber is realized by utilizing the photonic band gap effect or the total reflection principle, and in addition, the flexibility of the fiber and the low-loss transmission of the fiber at the bending radius of more than 2cm are ensured by utilizing the specific fact that the fiber main body material is a polymer material.

The optical fiber bullets can be selected in other shapes according to different operation requirements, so that holes in other forms can be prepared. In particular, if straight optical fiber bullets with different diameters are selected, the same principle can be used for drilling straight through holes or straight blind holes with different diameters.
Preferably, the optical fiber bullet adopts laser to automatically finish the polishing of the hole and the hole opening while preparing the hole: the edge of the pore passage, the edge of the inlet hole and the edge of the outlet hole are respectively and slowly burned by low-power laser to be polished and ground by utilizing the principle of laser polishing, and the pore wall can be smooth by polishing the pore passage and the pore opening while drilling, so that the rough surface of the pore passage and the rough surface of the pore opening are prevented from forming abrasion and cutting on the seam line, and the strength of the seam line is effectively protected.
