Description

Be applied to plastic surgery multi-angle D shape sword

Technical Field

The utility model belongs to the field of medical equipment, especially, relate to a be applied to plastic surgery multi-angle D shape sword.

Background

The D-shaped knife is one of scalpels, and mainly has the function of shoveling hard tissues such as cartilage in the operation, which is more common in orthopedic operations before, such as: when the operation is performed on the local defect and lesion of the cartilage, traumatic cartilage injury and osteochondritis adaptation diseases, the bone at the focus is chiseled, and then the healthy bone is taken and filled, namely, the bone transplantation operation is performed. The operation requires that the D-shaped cutter has the function of removing the spade, so that the common D-shaped cutter is linear and has a narrow cutter head width.

However, with the recent activation of plastic surgery, the D-blade is also used in plastic surgery, such as removal of costal cartilage. The conventional procedure is to open an opening in the patient's body and insert an instrument into the opening to perform extraction of the costal cartilage. The thickness of muscle tissue of different patients is different, and the depth of the opening is different, and the conventional straight D-shaped knife with shallow depth also has the operation space of a knife, and the common knife can damage the peripheral tissue of the opening under the condition of deeper depth. Therefore, the conventional linear D-shaped knife cannot fully satisfy the need for taking cartilage tissue in an orthopedic surgery.

Disclosure of Invention

Based on this, the utility model aims to provide a be applied to plastic surgery multi-angle D shape sword, this D shape sword is according to using the scene to get costal cartilage operation in the cosmetic plastic surgery promptly, and it can adjust advantages such as tool bit entering open-ended angle as required.

The technical scheme of the utility model is that: the utility model provides a be applied to plastic surgery multi-angle D shape sword, including the tool bit, the handle of a knife, wherein the tool bit passes through the connecting piece and is connected with the handle of a knife is articulated, the front end and the tool bit welded fastening of connecting piece, it is articulated with the handle of a knife to be connected through first articulated shaft in the middle of, the tail end passes through the second articulated shaft and is articulated with the driving medium, the driving medium passes through threaded connection and realizes relative motion with the lead screw, the lead screw is through detaining the cap spacing connect on the through-hole of handle of a knife radius of detaining the cap be greater than the through-hole of handle of a.

The lead screw is rotated after the equipment is good, because detain the cap and inject the lead screw in the through-hole of handle of a knife, the lead screw can't produce axial motion, and through the pushing action of screw thread, driving medium reverse motion, for example downstream, the driving medium drives the connecting piece tail end and sinks when downstream, because the fulcrum of the middle first articulated shaft of connecting piece produces leverage, the connecting piece anterior segment rises, and then forms corresponding angle with the handle of a knife.

The transmission structure enables the D-shaped knife to be in a linear state when the muscular tissue at the surgical opening of the patient is thin, and the screw rod is rotated to adjust a proper angle to use when the muscular tissue at the opening is thick, so that the D-shaped knife is simple in structure and convenient to operate. It is worth mentioning that: therefore, the transmission part is used as an intermediate transmission function, the screw rod is not directly adopted to control the connecting piece, the force arm track of the lever action is arc-shaped, the screw rod is linear, the screw rod and the screw rod cannot be matched for use, the transmission part is introduced, the transmission part is hinged with the connecting piece, when the transmission part is in position change due to the movement of the screw rod, the corresponding force action surface of the hinge is correspondingly changed, and in addition, the residual space between the hinged parts can completely meet the space regulation requirement of torque change.

Preferably, the handle of a knife is provided with the holding chamber and holds the driving medium and move along the lead screw axial in inside, and the driving medium makes whole utensil handheld more convenient, comfortable at the holding intracavity, and it will be explained here that the driving medium thickness is below half of the holding chamber height, just so makes tool bit angular adjustment space bigger.

Preferably, the width of driving medium is the same with holding chamber width, and when rotating the lead screw like this, the driving medium directly turns into along the axial up-and-down motion of lead screw because the limiting displacement in holding chamber does not produce and changes right, and the allowable machining precision's in the actual course of working deviation, the width of driving medium slightly is lighter than the width in holding chamber promptly.

Preferably, the width of the connecting piece is the same as that of the inner cavity of the handle hinged portion, so that the cutter head does not swing left and right in the use process of the cutter, and the deviation of machining precision is allowed in the actual machining process, namely the width of the connecting piece and the handle hinged portion is slightly smaller than that of the inner cavity of the handle hinged portion.

Preferably, the width of the handle accommodating cavity is smaller than or equal to the width of the inner cavity of the handle hinge part, and the arrangement is favorable for the integrated processing of the handle, such as turning and milling or pouring and drawing.

Preferably, the width of the tool bit is 8-12mm, the tool bit is wider than a conventional D-shaped tool, the bone can be shoveled once in the surgical plastic surgery, the plane of the shoveled cartilage is smooth, and convex grooves and the like generated by multiple operations are avoided.

Preferably, the end of the cutter head, which is far away from the connecting piece, is provided with an arc slope surface, and the arc slope surface of the cutter head can enable the cartilage to be automatically tilted and easily clamped out of the body in the operation process.

Preferably, the length of the connecting piece is 8-15mm, and the length enables the cutter head to be stressed evenly without effort of an operator.

Preferably, the buckle cap is provided with an adjusting groove, and the buckle cap can be rotated by inserting a straight screwdriver and the like into the adjusting groove so as to rotate the screw rod and adjust the angle of the connecting piece.

Implement the embodiment of the utility model provides a, following beneficial effect has:

the angle of this D shape sword can adjust tool bit and handle of a knife as required for the operation of operator is more convenient laborsaving under different operational environment, and tool bit width greatly makes this kind of D shape sword more be applicable to the advantage such as get cartilage operation among the plastic surgery operation simultaneously.
