Disclosed is a self-ligating orthodontic bracket which performs an orthodontic surgery by being fixed to a tooth. The disclosed self-ligating orthodontic bracket includes a bracket body including a slot formed in a first direction for insertion of a wire and a guide portion formed in a second direction crossing the first direction, a door installed in a reciprocally movable manner to the guide portion of the bracket body to open and close the slot, and a clamp installed between the bracket body and the door and allowing the door to move while being elastically deformed when a certain force is applied to the door in the second direction. The clamp includes a coupling pin having one end portion protruding toward the guide portion and installed to the bracket body, and an elastic ring installed to one side of the door opposite to the guide portion and formed of a single closed curve having a hollow.

The application relates to a simulation training instrument for upper eyelid ptosis correction surgery, and belongs to the technical field of medical devices, which comprises an eye use data collector and a simulation training table. The application provides a training instrument which can realize upper eyelid ptosis surgery simulation training and individualized simulation of the recovery of the upper eyelid levator muscle after correction surgery of a simulated patient, the setting of the eye use data collector is beneficial to the collection of individualized eye use data of the patient, so that the actual use of the eye muscle of the patient can be accurately simulated, the setting of the artificial muscle and the artificial fascia is beneficial to the training of the operator in a manner closer to the actual situation of the eye of the patient, and the simulation based on the collected eye data is beneficial to the simulation of the actual recovery of the patient after the surgery, so that the surgery scheme can be more accurately formulated according to the simulation result, the feasibility of the surgery scheme and the postoperative recovery effect are improved, and the success rate of the surgery is greatly improved through the simulation muscle surgery practice.

The application discloses a minimally invasive fixing device suitable for correction of a concealed penis, which is a non-surgical correction device, comprising a hollow puncture needle, a shrapnel assembly implantable into a human body and a medical suture; a shrapnel push rod capable of pushing the shrapnel assembly out of the puncture needle is arranged in the pipe body of the puncture needle; the shrapnel assembly is arranged in the puncture tip of the puncture needle in a curved shape and is automatically opened after being pushed out by the shrapnel push rod; one end of the medical suture is fixedly connected with the shrapnel assembly, and the other end is led out through the pipe body end of the puncture needle along the length direction of the puncture needle. The shrapnel assembly is bent and accommodated in the puncture tip of the puncture needle, the shrapnel push rod is used for pushing the shrapnel assembly out and automatically opening, and the rapid implantation and anchoring operation under a single puncture path are realized. The conventional general anesthesia correction operation can be replaced, no incision under local anesthesia, rapid correction are realized, and a non-surgical method for the concealed penis is realized, which is local anesthesia, super micro-invasive, rapid correction and safer.

The invention provides a femoral shaft osteotomy instrument, which relates to the technical field of orthopedic instruments and comprises a positioning nail, a connecting arm, a guide nail and a guide slide block. The positioning nail in the medullary cavity is forcibly associated with the external guide nail through the connecting arm, and the central axes of the positioning nail and the guide nail are always kept parallel, so that the parallelism of an osteotomy surface is ensured; and a rotary locking structure is arranged between the connecting arm and the mounting seat, and is matched with the design of the telescopic arm, so that flexible adjustment of multi-dimensional angles and lengths is realized. The guide sliding block slides along the guide nail and is provided with a damping structure, and accurate positioning and stable cutting of the osteotomy position are achieved by matching with a limiting ball of the cutting piece. The femoral shaft osteotomy orthopedic instrument solves the problems of non-parallel osteotomy surfaces, positioning deviation and inconvenience in adjustment of a traditional instrument, has the advantages of stable structure, accuracy in operation and high universality, and is suitable for various femoral shaft osteotomy orthopedic operations.

A screw for osteosynthesis includes a body, a thread, and a driver receiving cavity. The body includes a proximal end and a distal end, and the body defines a central longitudinal axis that extends between the proximal end and the distal end. The thread is disposed along at least a portion of the body. The driver receiving cavity is at the proximal end of the body, and the driver receiving cavity includes at least five lobes circumferentially spaced apart from one another about the central longitudinal axis to define at least five grooves. Each one of the at least five lobes defines a different internal lobular area. The at least five grooves can be configured to receive six lobes of a hexalobular driver having equally spaced lobes.
