[0046] Figure 1The figure shows a preferred embodiment of the surgical needle collection counter, which comprises a housing 1, a connecting component 2 and a pressing component 3;

[0047] The housing 1 is provided with an unclosed electric circuit for generating a magnetic field, an electronic magnetic induction counter 104, a display and a collection chamber 107; the electronic magnetic induction counter 104 is connected to the display;

[0048] The connecting component 2 is arranged in the housing 1, and the connecting component 2 is provided with an elastic unit 201. When the connecting component 2 is connected to the electric circuit, the electric circuit is closed to generate a magnetic field. At this time, the electromagnet inside the electric circuit generates a magnetic field to adsorb the surgical needle, and the electronic magnetic induction counter 104 senses the formation of the magnetic field to perform technology;

[0049] The pressing component 3 is arranged in the shell 1, and is provided with a channel for the needle holder 4 to enter but not completely pass through. The bottom of the pressing component 3 is provided with a bottom flange 304 in contact with the connecting component 2. Therefore, when the medical staff holds the needle holder 4 and places the surgical suture needle 5 into the pressing component 3, after placing it to a certain depth, the needle holder 4 cannot pass through and will cause the pressing component 3 to move downward. The pressing component 3 is provided with a bottom flange 304 in contact with the connecting component 2 at the bottom, which will drive the connecting component to move downward, so that when the connecting component 2 is connected to the electrical circuit in the shell 1, the electrical circuit is closed to generate a magnetic field.

[0050] like Figure 2 As shown, the electrical circuit in the housing 1 includes a wire, a power source 101, an electromagnet 102, and two first contacts 103;

[0051] The first contact 103, the wire, the electromagnet 102, the wire power supply 101, and the first contact 103 are connected in sequence to form an unclosed electrical loop.

[0052] Furthermore, the housing 1 is further provided with a first housing channel 105, a second housing channel 106 and a connection component cavity 110;

[0053] The first channel 105 of the housing is arranged at the top of the housing 1;

[0054] The connecting component cavity 110 is disposed below the first channel 105 of the housing;

[0055] The second housing passage 106 is disposed below the connection component cavity 110 and is smaller than the first housing passage 105 .

[0056] like Figure 3 and Figure 4As shown, a collecting chamber channel 108 is provided on the side of the collecting chamber 107 of the shell 1, and a collecting drawer 109 is provided in the collecting chamber channel 108. One side of the collecting drawer 109 is located outside the shell 1 and is provided with a handle.

[0057] like Figure 1 As shown, the connecting component 2 is disposed in the connecting component cavity 110, and the external shape is the same as the internal shape of the connecting component cavity 110;

[0058] like Figure 5 As shown, the connecting component 2 is provided with an elastic unit 201 on a side close to the second channel 106 of the shell, and the expansion and contraction direction of the elastic unit 201 is the same as the direction of the first channel 105 of the shell pointing to the second channel 106 of the shell; according to this embodiment, preferably, the elastic unit 201 is a spring.

[0059] The connecting component 2 is provided with two second contacts 202 on one side close to the second channel 106 of the housing; the two second contacts 202 correspond to the positions of the two first contacts 103 , and current can flow between the two second contacts 202 .

[0060] The connecting component 2 is provided with a connecting component channel 203 having the same shape and size as the second channel 106 of the housing.

[0061] like Figure 1 and Figure 6 As shown, the upper portion of the pressing component 3 is disposed in the first channel 105 of the housing and is slidably connected, and the lower portion is disposed in the second channel 106 of the housing and is slidably connected;

[0062] A top flange 301 is provided on the top of the pressing component 3, and the top flange 301 is stuck outside the first channel 105 of the shell, so as to play a limiting role, so that the pressing component 3 cannot completely enter the shell 1, which is convenient for subsequent removal of the pressing component 3.

[0063] like Figure 1 and Figure 7 As shown, the pressing component 3 is provided with a first pressing component channel 302 and a second pressing component channel 303;

[0064] The first channel 302 of the pressing component is for the needle holder 4 to enter and pass through;

[0065] The second channel 303 of the pressing component allows the needle holder 4 to enter but not pass through, so when the needle holder 4 is placed, the needle holder 4 will be stuck in the second channel 303 of the pressing component, thereby driving the pressing component 3 to move downward.

[0066] The bottom of the pressing component 3 is provided with a bottom flange 304;

[0067] The bottom flange 304 cannot pass through the connecting component passage 203 .

[0068] According to this embodiment, preferably, a one-way valve is provided at the bottom of the second channel 303 of the pressing component, and the one-way valve opens in the direction of the collecting chamber.

[0069] According to this embodiment, preferably, the pressing component 3 must meet the principle of sterility because it is in contact with the needle holder, so the pressing component 3 is a disposable sterile component and can be replaced at any time.

[0070] The working process of the utility model is as follows: when the surgeon needs to recycle the suture needle, first, the needle holder 4 clamps the suture needle 5 and extends it into the pressing component 3. When it extends into the second channel 303 of the pressing component, since the second channel 303 of the pressing component cannot allow the needle holder 4 to pass through, the needle holder 4 presses the pressing component 3 downward, and the pressing component 3 applies downward pressure to the connecting component 2. The spring of the connecting component 2 is compressed. When it is pressed down to the bottom, the second contact 202 of the connecting component 2 contacts the first contact 103 of the shell, forming a complete circuit. The electromagnet 102 generates a magnetic force to attract the suture needle 5. At this time, the needle holder 4 is released, and the suture needle 5 is attracted by the electromagnet 102 and falls into the collection drawer 109. Then the needle holder 4 withdraws from the pressing component 3, the pressing component 3 is separated from the connecting component 2, the electrical circuit is disconnected, the magnetic force of the electromagnet 102 disappears, and the electronic magnetic induction counter 104 senses a change in the generation and disappearance of the magnetic force and automatically counts once and displays it on the display. After the operation is completed, the collection drawer 109 can be directly pulled out from the collection chamber channel 108 for collection and replacement and manual confirmation of the quantity.

[0071] The utility model adopts the cooperation of the connecting component 2 and the pressing component 3. When the surgical needle is placed, the pressing component 3 presses the connecting component 2, so that the connecting component 2 and the electrical circuit in the shell 1 are completely closed, generating a magnetic field. The electronic magnetic induction counter 104 senses the change of the generation and disappearance of the magnetic force, automatically counts once and displays it on the screen, making the intraoperative collection and counting of surgical needles more convenient, avoiding manual counting errors, and reducing the risk of intraoperative needle loss and needle stick injuries to surgical personnel.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
