Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a minimally invasive breast surgery device. Background Art

[0002] The biopsy device is used to collect samples of active tissue. Some existing biopsy devices adopt a detachable structure. The biopsy needle is installed in the installation cavity of the biopsy handle and can be removed and replaced. The biopsy handle is provided with a tool detection device for detecting whether the biopsy needle is installed in place, which is used to prevent the handle from being pneumatically operated when the biopsy needle is not installed in place and causing accidents. In order to identify whether the biopsy needle tool is installed in place, there is a tool detection mechanism that sets a touch switch in the biopsy handle, opens a guide hole in the tool installation cavity, and sets a top sheath that can move along the guide hole in the guide hole. When the tool is installed in place, the top sheath is pushed by the tool to move toward the touch switch, which triggers the touch switch.

[0003] Theoretically, the touch switch can be triggered when the tool is installed in place, but in actual application, since the circuit board on which the touch switch is installed is tilted, the touch switch cannot be touched with the tail end of the top sheath, and the deformation of the spring of the touch switch is limited. The position and pressure of the top sheath and the touch switch are difficult to control accurately. Prolonged squeezing or excessive pressure may cause the touch switch to fail or be damaged. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a minimally invasive breast surgery device, which can reduce failure or damage caused by wear and fatigue of the mechanical structure in the handle and improve the accuracy of installation and identification of the biopsy needle assembly.

[0005] The utility model is realized by the following technical solutions:

[0006] A minimally invasive breast surgery device comprises an operating handle and a biopsy needle assembly detachably connected to the operating handle. The minimally invasive breast surgery device also comprises a host computer, a sensor and a circuit board. The circuit board is electrically connected to the sensor and the host computer at the same time. The circuit board is fixedly connected to the operating handle. The sensor is fixedly connected to the circuit board for detecting whether the biopsy needle assembly is installed in place.

[0007] Furthermore, the sensor includes a transmitting part for transmitting light signals and a receiving part for receiving light signals, and both the transmitting part and the receiving part are electrically connected to the circuit board.

[0008] Furthermore, the transmitting part and the receiving part are symmetrically arranged with respect to the biopsy needle assembly.

[0009] Furthermore, the sensor is an infrared sensor or a laser sensor.

[0010] Furthermore, the minimally invasive breast surgery device also includes a light-transmitting plate, and the light-transmitting plate is at least partially located between the sensor and the biopsy needle assembly.

[0011] Furthermore, the light-transmitting plate is detachably connected to the operating handle.

[0012] Furthermore, grooves are provided on both sides of the light-transmitting plate, and the operating handle has protrusions that are matched with the grooves.

[0014] Furthermore, the operating handle is provided with a rear hook, the biopsy needle assembly is provided with a buckle, and the rear hook is buckled with the buckle.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] 1. After the biopsy needle assembly is installed in place, the transmitting part emits a light signal that passes through the light-transmitting plate to reach the biopsy needle assembly. The light signal is reflected by the needle detection assembly and passes through the light-transmitting plate again to reach the receiving part. The circuit board converts the light signal received by the receiving part into an electrical signal to the host computer. By observing the host computer, it can be determined whether the biopsy needle assembly is installed in place. This device can reduce the failure or damage caused by wear and fatigue of the mechanical structure in the handle, and improve the accuracy of installation and identification of the biopsy needle assembly.

[0017] 2. A front hook and a rear hook that are engaged with the biopsy needle assembly are respectively provided at both ends of the operating handle, and whether the installation is in place can be judged by the sound when engaged. BRIEF DESCRIPTION OF THE DRAWINGS
