Description

Technical Field

[0001] This utility model relates to the technical field of percussion hammers, and in particular to the technical field of self-isolating percussion hammers. Background Technology

[0002] A percussion hammer is an instrument used to examine neuromuscular reflexes. It typically consists of a rubber hammerhead and a wooden or metal handle. When using it, doctors can gently tap the relevant area with the hammerhead to observe the neuromuscular reflexes. When a doctor uses the percussion hammer to examine a previous patient, the germs carried by that patient may remain on the hammerhead, potentially causing infection in subsequent patients. Therefore, doctors usually disinfect the hammerhead with a disinfectant after completing the examination.

[0003] To improve the convenience of examinations, some percussion hammers are equipped with disinfection mechanisms that spray disinfectant, such as the orthopedic surgeon's percussion hammer with announcement number CN213406098U and the neurosurgical percussion hammer with self-disinfection function with publication number CN113925539A. However, compared to wiping the hammer head with disinfectant using professional methods, directly spraying disinfectant onto the hammer head may leave blind spots in disinfection, especially if the disinfectant is not sprayed evenly or in insufficient quantity, thus posing a safety hazard. In addition, waiting for the disinfectant to dry is also time-consuming.

[0004] Some hospitals choose to use disposable plastic sleeves to cover the hammer head to isolate it from the patient; however, there are currently no disposable plastic sleeves specifically designed for covering hammer heads on the market, which results in disposable plastic sleeves covering the hammer head often being too large and easily falling off when not properly secured. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art by proposing a self-isolating percussion hammer that can use a disposable isolation sleeve to isolate the hammer head from the patient, and the disposable isolation sleeve is not easy to fall off.

[0006] To achieve the above objectives, this utility model proposes a self-isolating percussion hammer, comprising a hammer handle, a hammer tube, a hammer rod, and a disposable isolation sleeve. The hammer rod and the hammer tube are coaxially arranged and together form the hammer head. The top end of the hammer handle is fixed to the hammer tube. The disposable isolation sleeve is finger-shaped and can be fitted onto the striking end of the hammer head. The outer wall of the hammer tube is provided with an outwardly protruding annular convex wall. On the side of the annular convex wall facing away from the striking end, there is an annular groove into which the disposable isolation sleeve can squeeze its open end.

[0007] Preferably, the annular groove has a plurality of protruding teeth surrounding the groove wall.

[0008] Preferably, the hammer tube has an external threaded portion, and the screw sleeve is threaded to the external threaded portion of the tube and together with the hammer rod and the hammer tube to form the hammer head. When the screw sleeve is screwed, the end facing the striking end can be gradually inserted into the annular groove and pressed against the disposable isolation sleeve.

[0009] Preferably, the end of the threaded sleeve facing the striking end has a tapering portion that gradually narrows from the middle to the end.

[0010] Preferably, the device also includes a positioning bolt. The hammer rod passes through the hammer tube along the pipe. The hammer tube has a screw hole in its wall that connects to the outside and the pipe. The hammer tube also has a screw tube extending outward at the screw hole. The positioning bolt can be screwed into the screw hole along the screw tube until the screw tube and the hammer rod are supported against each other.

[0011] Preferably, the hammer handle has an internal cavity for inserting a disposable isolation sleeve.

[0012] Preferably, the hammer handle also includes a handle holder, the bottom end of which is provided with an external threaded portion. The handle holder includes a screw cap and a core rod. The screw cap is threadedly connected to the external threaded portion of the handle and fixed to the core rod. The core rod is placed in the cavity and can be fitted with a disposable isolation sleeve.

[0013] Preferably, the disposable isolation sleeve is also provided with an elastic rubber band at the open end that allows the opening to retract naturally.

[0014] The beneficial effects of this utility model are:

[0015] 1) This utility model connects the hammer handle and the hammer tube to form the hammer head, and adds an annular convex wall with an annular groove outside the hammer tube. This allows the disposable isolation sleeve to be squeezed into the open end of the disposable isolation sleeve when the doctor puts the disposable isolation sleeve on the striking end of the hammer head to isolate the hammer head from the patient, thus preventing the disposable isolation sleeve from falling off prematurely.

[0016] 2) By adding several protruding teeth around the annular groove wall, the present invention can use each protruding tooth to prevent the opening end of the disposable isolation sleeve from detaching from the annular groove, thereby further improving the anti-detachment property of the disposable isolation sleeve.

[0017] 3) This utility model uses a threaded sleeve with a constricting end to connect to the external thread of the hammer tube, so that the constricting end can be gradually inserted into the annular groove and pressed against the disposable isolation sleeve when the threaded sleeve is turned, effectively preventing the disposable isolation sleeve from falling off.

[0018] 4) This utility model provides a cavity inside the hammer handle and adds a handle frame consisting of a screw cap and a core rod at the bottom of the hammer handle. This allows the handle frame to be used to insert a disposable isolation sleeve roll into the cavity so that doctors can tear off a new disposable isolation sleeve from the disposable isolation sleeve roll at any time.

[0019] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description
