A puncture rack and a puncture rack kit

Abstract

The present invention relates to the technical field of puncture equipment, and in particular to a puncture stand and a puncture stand kit. The puncture stand includes a main body and a needle stand detachably connected to the main body; the main body includes a base plate with a first plane, and the needle stand includes a needle groove plate with a second plane. The first side of the second plane is provided with a needle groove. When the main body and the needle stand are connected, the second plane fits with the first plane to form a needle guide channel between the needle groove and the first plane. According to the technical solution provided by the present invention, when the snap-fit ​​structure is separated, in order to avoid the needle stand from contacting the main body and affecting the puncture needle, the needle plate moves in the opposite direction perpendicular to the first plane. In this way, the separation direction of the needle plate is opposite to the notch of the needle groove, which effectively reduces the probability of the needle body contacting the needle groove during the separation operation, thereby effectively reducing the probability of the needle stand touching the puncture needle, thereby reducing the impact on the puncture needle when the puncture stand is removed.

Description

Technical Field

[0001] The present invention relates to the technical field of puncture equipment, and in particular to a puncture rack and a puncture rack kit. Background Art

[0002] Ultrasound imaging equipment can display the patient's internal lesion area in real time, guiding the puncture needle to the target site under ultrasound guidance to perform cytological biopsy, histological biopsy, cyst aspiration, and treatment. Because the area displayed by the ultrasound probe is usually a flat surface, to ensure accurate puncture, a puncture holder is currently installed on the ultrasound probe to ensure that the puncture needle always remains on the ultrasound plane. This ensures that the puncture needle is always displayed on the ultrasound imaging device, allowing the doctor to adjust the puncture needle's insertion position and depth based on the image.

[0003] During actual surgical procedures, it is often necessary to remove the ultrasound probe first and temporarily retain the puncture needle to facilitate operations such as inserting a guidewire or drainage tube. To prevent the puncture needle from moving, extreme caution must be exercised when removing the ultrasound probe to ensure that the puncture needle is not touched. When using a puncture stand, the puncture stand must be removed at the same time as the ultrasound probe. Therefore, the puncture stand needs to have a needle stand detachment function. Currently, puncture stands with a needle stand detachment function are available, but with existing puncture stands, it is difficult to separate the puncture stand from the puncture needle without touching the puncture needle. Summary of the Invention

[0004] The present invention provides a puncture stand and a puncture stand kit, wherein the movement trajectory when removing the needle stand is perpendicular to the first plane. This method can effectively reduce the probability of contact between the needle stand and the main body during the separation operation, thereby reducing the impact on the puncture needle during the puncture stand removal operation.

[0005] One aspect of the present invention provides a puncture stand, comprising a main body and a needle holder detachably connected to the main body; the main body comprises a base plate having a first plane, the needle holder comprises a needle groove plate having a second plane, a needle groove is provided on a first side of the second plane, and when the main body and the needle holder are connected, the second plane is in contact with the first plane to form a needle guide channel between the needle groove and the first plane.

[0010] Optionally, the second plane includes a plurality of needle grooves, and the needle outlet ends of the plurality of needle grooves converge to form a needle outlet.

[0011] Optionally, a hand position is provided at one end of the first clipping plate and the second clipping plate away from the second side of the second plane; the height of the first clipping plate and the second clipping plate is higher than the height of the first fixed plate and the second fixed plate, and when the main body and the needle holder are connected, the hand position is located at the top of the first fixed plate or the second fixed plate.

[0016] According to the technical solution provided by the present invention, when the snap-fit ​​mechanism is separated, the needle plate moves in a direction perpendicular to the first plane in the opposite direction of the first plane to prevent the needle holder from contacting the main body and thus affecting the puncture needle.

[0027] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It will be understood that the specific embodiments described herein are intended only to explain the relevant content and are not intended to limit the present application. For the sake of simplicity, the same or similar reference numerals will be used in the description of the various embodiments of the present application for the same or similar devices / method steps.

[0028] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0029] Figure 1 Schematic diagram of the structure of the puncture frame provided by an embodiment of the present invention; Figure 2 is an exploded view of a puncture stand provided in an embodiment of the present invention; Figure 3 This is a schematic structural diagram of the main body of the puncture stand provided in an embodiment of the present invention; Figure 4 Schematic diagram of the structure of the needle holder in the puncture stand provided by the embodiment of the present invention. Figures 1 to 4As shown, the puncture frame includes a main body 1 and a needle holder 3 detachably connected to the main body 1; the main body 1 includes a first fixing plate 121, a second fixing plate 122 and a base plate 11 with a first plane, the needle holder 3 includes a first clamping plate 331, a second clamping plate 332 and a needle groove plate 31 with a second plane, and a needle groove 32 is provided on the second plane. When the main body 1 is connected to the needle holder 3, the second plane is fitted with the first plane to form a needle guide channel; the first fixing plate 121 and the second fixing plate 122 are respectively arranged perpendicular to the first plane, the first clamping plate 331 and the second clamping plate 332 are respectively arranged perpendicular to the second plane, and the first fixing plate 121, the second fixing plate 122 and the first clamping plate 331 and the second clamping plate 332 are respectively detachably connected through a clamping structure.

[0030] When using the puncture stand, select the appropriate guide needle channel, and then rely on the puncture stand to insert the puncture needle into the human body along the guide needle channel (specified angle). When the puncture needle and the puncture stand need to be separated, press the first clamping plate 331 and the second clamping plate 332 toward the midline, so that the first clamping plate 331 and the second clamping plate 332 are connected to the second plane at a certain elastic deformation, so that the clamping structure is in a separated state. At this time, the needle holder 3 is separated in a direction perpendicular to the first plane and the second plane. In this direction, the first fixing plate 121, the second fixing plate 122 and the first clamping plate 331, the second clamping plate 332 are parallel to each other, and there is no other obstruction. Therefore, during the separation operation, the probability of contact between the main body 1 and the needle holder 3 can be reduced, thereby reducing the impact on the puncture needle.

[0031] like Figure 1 and Figure 2 As shown, in the embodiment of the present invention, the puncture frame further includes a locking device 2, which is detachably connected to the base plate 11. The ultrasonic probe is connected to the base plate 11 through the locking device 2, thereby achieving a detachable connection between the ultrasonic probe and the puncture frame.

[0032] like Figures 2 to 4As shown, the snap-fit ​​structure includes a snap 15 and a protrusion 34. The snap 15 is provided on the first and second fixing plates 121, 122, and the protrusion 34 is provided on the first and second fixing plates 331, 332. Alternatively, the snap 15 is provided on the first and second fixing plates 331, 332, and the protrusion 34 is provided on the first and second fixing plates 121, 122. The snap 15 and the protrusion 34 are removably connected by elastic deformation of the first and second fixing plates 121, 122, and / or the first and second fixing plates 331, 332. The protrusion 34 protrudes from the snap 15 to ensure that it can be disengaged during the separation operation. The protrusion 34 and snap 15 structure facilitates both installation and removal of the main body 1 and the needle holder 3.

[0033] Continue to refer Figures 1 to 4 In the embodiment of the present invention, the first and second fixing plates 121, 122 are perpendicularly disposed on either side of the first plane, thereby forming a groove-shaped structure with the first plane. The width of the first end of the groove-shaped structure is greater than the width of the second end. A first and second clipping plates 331, 332 are disposed opposite each other on the second side of the second plane. The first fixing plate 121 engages with the first and second clipping plates 331, 332, respectively. During the separation operation, one hand presses the first and second clipping plates 331, 332, respectively, causing them to deform toward each other and separate from the first and second fixing plates 121, 122, respectively. The hand then continues to hold the first and second clipping plates 331, 332, to separate the needle holder 3 from the main body 1. This structural form effectively reduces the difficulty of the separation operation, allowing the separation operation to be completed with one hand.

[0034] In an embodiment of the present invention, the first plane and the second plane are shaped like a "V", including a set of opposing inclined edges. The first fixing plate 121 and the second fixing plate 122 are perpendicular to the inclined edges of the first plane, and the first clip plate 331 and the second clip plate 332 are perpendicular to the inclined edges of the second plane. The main body of the base plate 11 and the needle groove plate 31 is approximately a "V"-shaped structure, and the angles of the corresponding first fixing plate 121, the second fixing plate 122, and the first clip plate 331 and the second clip plate 332 are also arranged in a "V". With this structure, the second plane of the needle body includes multiple needle grooves 32 with different angles. The needle outlet ends of the multiple needle grooves 32 converge to form a needle outlet 35. The "V"-shaped second plane facilitates the arrangement of the needle grooves 32.

[0035] like Figure 1 、 Figure 2 and Figure 4As shown, a hand position 37 is provided at one end of the first and second clipping plates 331, 332, away from the second side of the second plane. The height of the first and second clipping plates 331, 332 is higher than that of the first and second fixing plates 121, 122. When the first and second fixing plates 121, 122 are connected to the first and second clipping plates 331, 332, the hand position 37 is located at the top of the first and second fixing plates 121, 122. When the needle body is installed or removed from the main body 1, manual pressure is required on the first and second clipping plates 331, 332 to cause them to elastically deform. The provision of the hand position 37 further facilitates the application of pressure on the first and second clipping plates 331, 332, as well as the removal of the first and second clipping plates 331, 332. In embodiments of the present invention, the hand position 37 may be provided with anti-slip grooves and a reminder label, such as a pressure reminder arrow.

[0036] In the embodiment of the present invention, a positioning structure is further provided between the first plane and the second plane. The purpose of the positioning structure is to limit the relative movement of the main body 1 and the needle holder 3, so that the puncture needle in the needle groove 32 is relatively stable. Figure 3 and Figure 4 As shown, the positioning structure includes a positioning protrusion 13 and a positioning groove 36; the positioning protrusion 13 is arranged on the first plane, and the positioning groove 36 is arranged on the second plane, or the positioning protrusion 13 is arranged on the second plane, and the positioning groove 36 is arranged on the first plane; when the second plane is used to fit with the first plane, the positioning protrusion 13 is inserted into the positioning groove 36.

[0037] like Figure 2 and Figure 3 As shown, the main body 1 further includes a marking plate 14, which is disposed at the first end of the base plate 11. The marking plate 14 is provided with angle markings corresponding to the guide needle channels. Angle markings such as 0, 15, 30, etc., correspond to puncture angles of 0 degrees, 15 degrees, and 30 degrees.

[0038] Figure 5 Schematic diagram of the structure of the puncture frame kit provided by the embodiment of the present invention. Figure 5 As shown, the puncture frame kit includes the above-mentioned main body 1 and multiple needle frames 3; the widths of the needle slots 32 in the multiple needle frames 3 are different, and different needle frames 3 are used to be combined with the main body 1 to form needle guide channels of different widths.

[0039] like Figure 5 As shown, a model label is provided on the back side of the second plane. Different models of needle holders 3 have different angles or widths of the needle groove 32 on the second plane. In the puncture holder kit, one base plate 11 is adapted to multiple needle holders 3, which improves the versatility of the product and reduces the design and manufacturing costs of the puncture holder.

[0040] The above specific embodiments do not limit the scope of protection of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may occur depending on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention.
