Abstract
The utility model relates to a splash-proof bone grafting device, and belongs to the field of medical equipment. The splash-proof bone grafting device is used for grafting bones in the process of orthopedic operation. A funnel for grafting the bones consists of a tamper (1) and a funnel (2). The splash-proof bone grafting device is characterized in that the tamper (1) consists of a tamper rod (3), a funnel cover (4), steel balls (5), a spring (6), a pin nail (7) and a handle (8), where the tamper rod (3) is in a shape of a step rod, the head part at the left end is in a spherical shape, and a through hole is formed at the right end; a through hole is formed in the center of the funnel cover (4), an annular groove is formed at the lower end, and a through groove is formed at the right end; the funnel (2) consists of a funnel body (9), a connecting rod (10), the pin nail (7) and the handle (8); a through hole is formed in the center of the funnel body (9), the upper part is in a cone shape, the lower part is in a cylindrical shape, and an oblique cone opening is formed at the lower end of the funnel body (9); and scale marks are formed on the cylindrical surface. According to the splash-proof bone grafting device, the operation position and the implantation depth and direction of the splash-proof bone grafting device are determined first, holes are drilled, broken bones are put into the funnel (2), and the bones are grafted by combining the tamper (1) and the funnel (2) until the requirement of operation is met.
Description
Technical field
This utility model relates to a kind of splashproof bone grafting device, belongs to medical instruments field, is used for bone surgery process bone grafting.
Background technology
The bone grafting methods that adopt when in bone surgery, treating patient's bony defect at present or removing downright bad part more; Common operation method has armrest art doctor boring, utilizes pliers implantable artificial bone, allograph bone then or from the body bone, or adopts funnel to cooperate the method bone grafting of bone grafting rod; Adopt funnel to cooperate simple to operation, the safety of method of bone grafting rod bone grafting at present; Shorten operating time, reduce the patient suffering, help the quickly-healing of performing the operation, but broken bone is spilt.
Summary of the invention
This utility model under the prerequisite that keeps the prior art advantage, overcomes its drawback just, provide a kind of in operation process, have simple in structure, easy to operate, be difficult for splashproof bone grafting device that broken bone is spilt.
The technical scheme of this utility model is following:
Splashproof bone grafting device is made up of tamper (1), funnel (2).It is characterized in that: tamper (1) is made up of tamper body (3), filler cap (4), steel ball (5), spring (6), pin (7), handle (8), and tamper body (3) is that step is shaft-like, and the left end head is spherical, and right-hand member has through hole perpendicular to the central axis place; Filler cap (4) central through hole, there is annular groove the lower end, and right-hand member has the semi arch groove.Funnel (2) is made up of infundibular body (9), connecting rod (10), pin (7), handle (8), infundibular body (9) central through hole, and top is cone-shaped, and the bottom is cylindric, and there is oblique conical opening its lower end, and cylindrical surface has the groove labelling, is convenient to selectivity and implants broken bone.
Tamper (1): filler cap (4) passes tamper body (3), under the effect of steel ball (5) and spring (6), is fixed on the tamper body (3), and tamper (1) and funnel (2) are when being used; Filler cap (4) is moved from tamper body (3), and filler cap (4) is tight with infundibular body (9) upper end awl flap, at this moment; Filler cap (4) right-hand member semi arch groove just in time is stuck on the connecting rod (10), is convenient to broken bone and implants, and realizes preventing the function that broken bone spills; Tamper (1) can be designed plurality of specifications, selects for use when supplying operation.
Funnel (2): infundibular body (9) bottom is cylindric, and there is oblique conical opening its lower end, makes funnel (2) be convenient to insert in the damaged bone cavity; Groove labelling through observing infundibular body (9) cylindrical surface is inserted into the appropriate location in the bone cavity with funnel (2), in infundibular body (9), puts into an amount of broken bone, and broken bone is implanted to defect under the effect of tamper (1); To the demand of performing the operation, utilize splashproof bone grafting device bone grafting can increase bone grafting density, healing has obvious effects to corrective surgery; And shortening operating time; Reduce the patient suffering, funnel (2) can be designed plurality of specifications, selects for use when supplying operation.
This utility model is applicable to bone grafting in the bone surgery process, and implantable artificial bone, allograph bone or from the body bone have the advantage that easy to operate, safe, broken bone is difficult for spilling.
Through diagnose medical conditions such as CT or X-ray before the art, implement operation: confirm bone grafting position and broken bone quantity.At first confirm surgery location, confirm the degree of depth and the orientation of splashproof bone grafting device implantation, implement boring, broken bone is inserted in the funnel (2), removable hopper lid (4) cooperates infundibular body (9), prevents that broken bone from spilling, and unites funnel (2) bone grafting to requirements of operation with tamper (1).
This utility model is applicable to bone grafting in the bone surgery process; Implantable artificial bone, allograph bone or from the body bone; That splashproof bone grafting utensil has is simple in structure, easy to operate, safe and reliable, prevent the function that broken bone spills, the advantage of advanced design, is suitable for the orthopaedics clinical application.
