A universal matching water spray device for orthopedic grinding and drilling

Abstract

The invention belongs to the technical field of medical devices, and specifically relates to a universal water spray device for orthopedic grinding and drilling, including a fixing ring. The side wall of the fixing ring is symmetrically provided with two threaded holes, and the threaded holes are threaded with limit bolts. The limit bolt is used to fix the drill, and the side wall of the fixing ring is equidistantly fixed with more than two telescopic rods along its circumference. The surface of the telescopic rods is wound with a return spring, and the telescopic rods are far away One end of the fixed ring is fixed with a No. 1 ring, and the two ends of the return spring are respectively fixed on the fixed ring and the No. 1 ring. The No. 1 ring is a cavity structure; the present invention attaches the No. 2 ring to the surface of the patient's bone , so that the water sprayed on the surface of the patient's bone for cooling cannot flow and drip freely, and realize the recovery of cooling water, thereby ensuring the cleanliness of the operation site, avoiding the flow of cooling water, and thus avoiding pollution to surgical equipment.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a universal matching water spray device for orthopedic grinding drills. Background technique [0002] Orthopedics is also called orthopedics. It is a profession or discipline of medicine, specializing in the study of the anatomy, physiology and pathology of the musculoskeletal system, using drugs, surgery and physical methods to maintain and develop the normal form and function of this system, and to treat injuries and diseases of this system. During orthopedic surgery, a large number of orthopedic drills are used. In order to avoid the heat generated by the high-speed grinding of bone during the use of the drill to damage the bone cells, it is usually necessary for an assistant to use a syringe to inject water into the grinding area to lower the drill bit and grind the bone surface. local temperature. However, this process requires the good cooperation of t...

Problems solved by technology

[0007] The technical solution adopted by the present invention to solve the technical problem is: a universal matching water spray device for orthopedic grinding and drilling according to the present invention, comprising a fixed ring, the side wall of the fixed ring is symmetrically provided with two threaded holes, and the threaded hole is The limit bolts are threaded to fix the drill, and the side wall of the fixing ring is equidistantly fixed with two or more telescopic rods along its circumferential direction, and the surface of the telescopic rods is wound with a return spring , the end of the telescopic rod away from the fixed ring is fixed with a ring, the two ends of the return spring are respectively fixed on the fixed ring and the first ring, the first ring is a cavity structure, and the inner part of the first ring The cavity is provided with a water inlet pipe, and the end of the water inlet pipe away from the No. 1 ring is connected to a water pump. The water inlet of the water pump is provided with a connecting pipe for connecting the pool. A guide rod is fixed equidistantly along its circumference, the guide rod is a cavity structure, the cavity of the guide rod communicates with the cavity of the No. 1 ring, and one end of the guide rod away from the No. No. 1 sprinkler head, the end of the guide rod away from the No. 1 ring is fixed with No. 2 ring, and the section width value of the end of the No. 2 ring close to the No. One end of the ring is fixed with a sealing ring, the sealing ring is made of silica gel material, the guide rod is located on the inner wall of the second ring, the side wall of the second ring is provided with a water outlet hole, the water outlet hole is a flat structure, The water outlet hole is located at the bottom of the inner wall of the second ring, and a drain pipe is provided at the water outlet hole, and the drain pipe is used to discharge sewage, and a switch is provided on the fixed ring, and the switch is electrically connected to the water pump; The water device does not recycle the injected water. For operations that require long-term drilling, such as craniotomy, it is often necessary to spray more water. The sprayed water flows everywhere without recycling, which is extremely difficult. It is easy to cause the operating table to be polluted, thereby affecting the operation. The present invention solves this problem; before performing the operation, the placement position of the skull is adjusted, and the skull is fixed so that the drilling position of the skull is horizontal or inclined Upward state; pass the shell of the drill through the fixing ring, and turn the limit bolt, the distance between the limit bolt and the shell of the drill will be shortened under the action of the threaded hole and the shell of the drill will be tightened, so that the drill The shell is limited, and the connecting pipe is put into the pool at the same time; start the drill to rotate the drill bit, and at the same time fill the pool with water and start the water pump through the switch, and then attach the second ring and the sealing ring to the hole to be drilled position, and align the drill bit with the drill point so that the drill point is located at the center of the second ring; then the user moves the drill shell towards the skull so that the drill bit is close to the patient's Skull, the No. 2 ring and the sealing ring are against the skull when the drill bit is approaching. When the drill housing moves, the telescopic rod and the return spring are squeezed, so that the drill bit can move normally and the No. 2 ring remains The water pump sends the water in the pool into the cavity of the No. 1 ring, so that the cooling water moves from the cavity of each guide rod to the No. 1 nozzle and sprays from the No. 1 nozzle; No. 1 nozzle sprays Out of the cooling water sprayed on the table of the patient's skull surface, so that the heat generated when the drill bit is drilled is taken away, and the cooling water flows down the surface of the patient's skull to the inner surface of the second ring, because the sealing ring blocks the gap between the second ring and the skull Make the cooling water gather between the inner ring of the second ring and the skull; because the cross-sectional width of the second ring has a gradient, the height of the end of the second ring close to the patient’s skull is lower than the height of the end of the second ring away from the skull, so that the flow The cooling water that comes down gathers in the second ring near the side of the skull; when the cooling water gathers in the second ring, it moves to the water outlet hole and enters the water outlet hole, and the cooling water flows out from the drain pipe, realizing the cooling water. To recycle, just put the drainage pipe into the waste water recycling device; the present invention attaches the No. 2 ring on the surface of the patient’s skull, so that the water sprayed on the surface of the patient’s skull for cooling cannot flow freely and drip, and realize the cooling of the cooling water. recycling, thus ensuring the cleanliness of the surgical site, avoiding the flow of cooling water, thereby avoiding the contamination of surgical equipment; at the same time, the cooling water sprayed from multiple No. 1 nozzles covers the patient's skull, so that the heat during the drilling process is absorbed Absorb in time to avoid the problem of patient injury due to high temperature generated by drilling; in addition, the skull powder and bone slag produced during the grinding and drilling process are dissolved in the cooling water in time, thereby reducing the splash of bone slag, which not only protects the The cleanliness of the on-site environment also avoids harm and impact on medical staff
