Description
Technical Field
The utility model belongs to the field of medical equipment, specifically a bone tissue holder.
Background
Dental implant restoration is one of the most common methods for restoring intraoral missing teeth, and bone grafting is often required in dental implant surgery due to insufficient bone mass in the missing tooth area. While autogenous bone is the most ideal bone grafting material, bone graft is a common intraoral autogenous bone grafting method.
At present, due to the lack of suitable instruments, some traditional instruments used in oral tooth extraction are often used in autologous bone transplantation, such as a dental elevator used in bone tissue separation, hemostatic forceps used in bone tissue extraction, and common forceps used in bone tissue holding. The instrument greatly increases the technical sensitivity in operation, and is easy to cause pollution and even bone extraction failure. For example, ordinary forceps can be used to hold instruments and articles for oral procedures, but since autologous bone tissue is at a premium, the forceps can be inadvertently dropped into a patient's mouth or even the ground during the procedure, resulting in failed procedures.
Therefore, the oral cavity autologous bone transplantation performed by using the existing instrument has higher technical sensitivity, is only borrowed into the autologous bone transplantation operation when needed, is not a matched tool designed based on the bone transplantation, and is easy to fail.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a bone tissue holder can be used to the cubic bone transplantation of oral cavity jaw facial portion, for the bone piece punch in the art, place and supply the district, stabilize the bone tissue of holding in fixed operation steps such as, prevent that bone tissue from dropping the pollution, solved in the past the problem that cubic bone transplantation lacks suitable apparatus, reduce the technical sensitivity, increase the operation success rate, reduce the degree of difficulty that doctor operated, it is painful to reduce the patient, do benefit to the operation prognosis.
The technical scheme of the utility model is that:
a bone tissue holder comprises a bent forceps handle and two forceps arms extending from two ends of an opening of the forceps handle, wherein the top ends of the two forceps arms are respectively provided with a C-shaped forceps head; the C-shaped openings of the forceps heads face the inner sides of the two forceps arms, and C-shaped bottom plates are arranged at the openings along the inner walls of the bottom ends of the forceps heads.
When the two forceps heads are closed, the end parts of the two bottom plates are connected, and the middle parts of the two bottom plates are hollowed out.
The C-shaped bottom plate on the bone tissue holder is an inclined plane, and the bottom end of the inclined plane faces to the center of the forceps head.
The forceps arms on the bone tissue holder are respectively provided with a threaded through hole and a threaded rod, the threaded rod penetrates through the two through holes, and one end of the threaded rod is provided with a limiting block.
The technical effects of the utility model are that:
1. bone tissue holder, "C" shape tweezers head inner wall and "C" shape bottom plate can be formed with the baffle and have the similar recess that the bottom plate supported around the interval, and bone tissue places this interval in, connects bone tissue by the bottom plate flourishing, only needs to pinch tightly the tweezers arm, just can hold bone tissue well, prevents that bone tissue from dropping the pollution.
2. The bottom plate is the inclined plane, and the inclined plane bottom is towards tweezers head center, fretwork position promptly can help the garrulous end discharge when blood and drilling, reduces and washes the step.
3. The treated bone tissue is convenient to place in the receiving area, and only the forceps arms need to be loosened.
A bone tissue holder punches, places for the bone piece in the art and supplies district, stable holding bone tissue in the operation steps such as fixed, prevents that bone tissue from dropping the pollution, has solved the problem that cubic bone transplantation lacked suitable apparatus in the past, reduces the technological sensitivity, increases the operation success rate, reduces the degree of difficulty that the doctor operated, reduces patient's misery, does benefit to operation prognosis.

Detailed Description
The present invention will be further described with reference to the following examples.
After the bone tissue is taken out, the bone tissue needs to be drilled and placed in a receiving area, and strict aseptic operation is needed in the process so as to reduce postoperative complications such as infection. And bone tissue holder structure can reach this purpose well, bone tissue holder possess the foundation structure of tweezers, can form the similar recess region of stably placing and fixing bone tissue at the tip simultaneously, the recess center still has the fretwork, conveniently drills on bone tissue to and discharge away sewage when wasing. As shown in the examples below.
As shown in fig. 1-2, the bone tissue holder is shaped like a forceps as a whole, and comprises a bent forceps handle 1 and two forceps arms 2 extending from two ends of an opening of the forceps handle 1. The included angle of the bending part of the forceps handle 1 is 15 degrees, the width is 8.5mm, the length is 159mm, and the outer surface of the handheld part is designed to be a strip-shaped fingerprint so as to increase the friction coefficient and facilitate holding. The forceps arm 2 is gradually narrowed to 5mm in width and 100mm in length. Threaded through holes 3 and threaded rods 4 are respectively arranged on the two forceps arms 2, the threaded rods 4 penetrate through the two through holes 3, a limiting block 5 is arranged at one end of each threaded rod 4, and the distance between the two forceps arms 2 is adjusted by rotating the threaded rods 4. The top ends of the two forceps arms 2 are respectively provided with a C-shaped forceps head 6; the C-shaped opening of the forceps head 6 faces the inner sides of the two forceps arms 2, a C-shaped bottom plate 7 is arranged at the opening along the inner wall of the bottom end of the forceps head 6, the C-shaped bottom plate 7 is 7mm in width, and when the forceps head 6 is closed, the end parts of the two bottom plates 7 are connected, and the middle part of the two bottom plates is hollowed out. The bottom plate 7 of the bone tissue holder and the inner wall of the forceps head 6 form a safe holding area, and the bone tissue is taken out and placed in the holding area. After the bone tissue holder clamps the bone tissue, the bone tissue can be drilled, and the hollow-out formed between the bottom plates 7 is convenient for punching the bone tissue.
Example 2
As shown in fig. 3-4, the basic structure of the bone tissue holder in embodiment 2 is similar to that in embodiment 1, except that the C-shaped bottom plate 7 in embodiment 2 is a slant, the bottom end of the slant faces the center of the forceps head 6, and the slant formed by the bottom plate 7 facilitates the discharge of blood and debris during the perforation of bone tissue, and reduces the operations such as flushing to better avoid the contamination problem such as falling of bone tissue.
A bone tissue holder, oral cavity autologous bone take out the back, can punch for the bone piece in the art, place and supply the district, stabilize holding bone tissue in fixed operation steps such as, prevent that bone tissue from dropping the pollution, solved in the past that cubic bone transplantation lacks the problem of suitable apparatus, reduce the technological sensitivity, increase the success rate of performing the operation, reduce the degree of difficulty of doctor's operation, it is painful to reduce the patient, does benefit to the operation prognosis. Besides being used for autologous bone transplantation of oral and maxillofacial regions, the utility model can also be used for bone transplantation operations of other parts of the whole body, and autologous bone transplantation or allogeneic bone transplantation operations of animal experiments such as small pigs and beagles.
