Abstract
The utility model discloses an intervertebral disc hook. The intervertebral disc hook comprises an anti-skid head (1), a handle (2), a connecting rod (3) and a tool bit (4), wherein the anti-skid head is connected with the handle; an anti-skid groove is arranged between the anti-skid head and the handle; the handle is connected with the connecting rod; and the other end of the connecting rod is connected with the tool bit to form a right angle. According to the intervertebral disc hook, the anti-skid groove is arranged between the anti-skid head and the handle, so that an instrument is effectively prevented from skidding during a surgery; the handle and the connecting rod are thinned gradually, so that the relatively thick handle is in favor of transmitting a tool gripping force and exerting a relatively large force, and the relatively thin connecting rod is in favor of extending into a gap between centrums; the tool bit is relatively narrow, so that size of an opening and the injury on a human body are reduced as much as possible when the tool bit enters the human body; the outer side of the tool bit is sharp so as to cut away the ossific intervertebral disc; and the inner side of the tool bit is blunt, so that the injuries on other part of the vertebra and nerves are reduced. The intervertebral disc hook has the characteristics of sturdy and durable performance, convenience in operation, reduced surgical injury and low cost.
Description
Technical field
This utility model belongs to technical field of medical instruments, and is specifically a kind of easy to be easy-to-use, the lumbar diskectomy of giving prominence to and ossify can be got off, and reduces the intervertebral disc billhook of operation wound simultaneously.
Background technology
Intervertebral disk hernia is also ossified is the commonly encountered diseases of spinal surgery, and this disease serious normal operation that affects the patient, living and studying cause no small misery to the patient.At present, clinical Therapeutic Method is by operation, ossified lumbar diskectomy is got off and takes off.Owing to still there is no at present special-purpose operation tool, and the instrument termination that substitutes is larger, not only can increase surgical wound from external when entering in body, cause hemorrhage and to spinoneural interference, and complicated operation, operating time long, human body is had certain infringement.
Summary of the invention
The purpose of this utility model namely produces thus, proposes a kind of intervertebral disc billhook, reaches the increase success rate of operation, reduces operation wound, hemorrhage and to spinoneural interference, shortening operating time, purpose easy and simple to handle.Have sturdy and durable, easy and simple to handle, reduce surgical injury, the characteristics such as with low cost.
For achieving the above object, the technical scheme that this utility model is taked is: a kind of intervertebral disc billhook comprises anti-slippery fellow, handle, connecting rod and cutter head, anti-slippery fellow is connected with handle, has anti-slip tank between anti-slippery fellow and handle, handle is connected with connecting rod, and the other end of connecting rod meets at right angles with cutter head and is connected.
Anti-slippery fellow described in the utility model is solid construction, and top ends is cylindrical, with the diameter of the handle link diameter less than top end diameter and handle.
Handle described in the utility model is solid construction, is six prismatics, and the surface is provided with the annular knurl decorative pattern.
Connecting rod described in the utility model is solid construction, is four prismatics.
Handle described in the utility model and the connecting rod gradually fine texture of serving as reasons slightly.
Long 1.8 centimetres of cutter head described in the utility model, wide 0.4 centimetre, cutter head is gradually narrow structure, and head is point of a knife.
This utility model is reasonable in design, and end, the anti-skidding crown is cylindrical structure, and less than top end diameter, this structure can be stuck in pinkie anti-foxy cervical region when holding this intervertebral disc billhook, prevent the apparatus landing with the diameter of handle link; Handle and connecting rod are the structure that is tapered, the conduction of strength and apply larger strength when thicker and solid handle is conducive to hold cutter, and thinner connecting rod is conducive to go deep in interbody space; Handle is six prismatics, and it is not only attractive in appearance to have knurled pattern, can also increase the frictional force of handle and hands, makes that to hold cutter more firm; Cutter head is narrower, reduces the size of opening and the injury that human body is caused when entering human body as far as possible; Cutter head outside one side is sharp, is suitable for cutting away ossified intervertebral disc, and inboard one side is blunt type, reduces other positions of vertebra and the neural injury that causes; Cutter head 1.8 centimeter length, 0.4 centimetre of the widest part, leading portion are pointed, from gradually thin to tip with the connecting rod junction, can reduce the injury that when entering human body, tissue is caused and increase simultaneously its sharpness.The characteristics such as that whole design has is sturdy and durable, easy and simple to handle, reduce surgical injury, with low cost.
Description of drawings
Fig. 1 is the structural representation of utility model.
In figure: 1, anti-foxy, 2, handle, 3, connecting rod, 4, cutter head.
The specific embodiment
By reference to the accompanying drawings, provide embodiment of the present utility model as follows:
As shown in Figure 1: a kind of intervertebral disc billhook comprises anti-slippery fellow 1, handle 2 and connecting rod 3 and cutter head 4, and anti-foxy 1 is connected with handle 2, has anti-slip tank between anti-slippery fellow and handle, and handle 2 is connected with connecting rod 3, and the other end of connecting rod 3 meets at right angles with cutter head 4 and is connected.Anti-foxy 1 is solid construction, and its top ends is cylindrical structure, with the diameter of the handle link diameter less than top end diameter and handle 2, thus, forms anti-slip tank between anti-slippery fellow and handle.This structure can be stuck in pinkie anti-foxy cervical region when holding this intervertebral disc billhook, prevent the apparatus landing.The appearance of handle of a knife 2 is six prismatics, and the surface is provided with knurled pattern, and is not only attractive in appearance, can also increase the frictional force of handle of a knife and hands, makes that to hold cutter more firm.Handle 2 is connected with the connecting rod 3 of four prismatics, and handle and connecting rod are the structure that is tapered, and the conduction of strength and apply larger strength when being conducive to hold cutter when connecting rod gradually carefully is conducive to enter in human body, causes as far as possible little otch to enter.Anti-foxy 1 in the present embodiment, handle 2, connecting rod 3 and cutter head 4 are solid, can use larger strength with ossified lumbar diskectomy the time.One end of connecting rod is connected with handle 2, the other end meets at right angles with cutter head 4 is connected, and is beneficial to the strength that puts on handle and all passes to cutter head.Cutter head 4 is narrower, length is 1.8 centimetres, 0.4 centimetre of the widest part, the injury of cutter head from narrowing down gradually and human body is caused can reduce to greatest extent billhook and enter human body the time to taper with connecting rod, cutter head outside one side is sharp structure, be conducive to ossified lumbar diskectomy is got off, inboard one side is blunt type, reduces the injury to other positions of vertebra and spinal cord.
During use, hold the handle with annular knurl, make cutter head enter into intervertebral space by skin incision, the lumbar diskectomy that utilizes the sharp one side in the cutter head outside to give prominence to and to ossify gets off.
