Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a fixation bracket and endoscope system for an endoscopic diagnostic and treatment instrument. Background Technology

[0002] With the development of digestive endoscopic treatment technology, its applications have expanded from the removal of small polyps to the dissection of large-area early cancers, and from the surface of the digestive tract lumen to the digestive tract wall, and even beyond the digestive tract wall into body cavities. Endoscopic diagnostic and treatment techniques are widely used in clinical practice. During endoscopic procedures, the endoscopist typically operates the endoscope with their left hand and the insertion part with their right. If diagnostic instruments are used, a surgical assistant holds the instrument's handle to control the front treatment end, while the endoscopist controls the instrument's movement with their right hand.

[0003] During the perioperative period, the endoscopist and surgical assistant stand side by side. The endoscopist uses their right hand to control the instruments, guiding them through the endoscope's instrument channel into the patient's body; the surgical assistant operates the instruments' handles, controlling their extension, opening, closing, and rotation under the endoscopist's verbal instructions. During the procedure, if the endoscopist suddenly rotates the endoscope or changes their surgical position, the surgical assistant may not respond promptly, causing the instruments to malfunction and pull on the endoscopist's movements, potentially even causing the instruments to slip out of the endoscope's instrument channel. Furthermore, this current approach increases labor costs. Therefore, there is an urgent clinical need for a solution that allows endoscopists to independently perform endoscopic procedures. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides an endoscopic diagnostic and treatment instrument fixation bracket and an endoscope system, which can solve the problem that endoscopists cannot independently complete the diagnostic and treatment procedures in the existing technology.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] An endoscopic diagnostic instrument fixation bracket includes: a bracket portion, which includes a base; a clamping portion, which includes a fixing platform, a guide rail, a pair of first springs, a pair of first posts, and a pair of limiting balls. The fixing platform is positioned near one end of the base. The guide rail passes through the fixing platform in a first direction, and both ends of the guide rail pass through the first springs and the first posts, respectively, and are connected to the limiting balls. The first posts can be inserted into a pair of symmetrically arranged finger rings in a ring-shaped operating handle; and a locking portion, which includes a locking base, a second post, and a second spring. The locking base has an inner cavity, and the second post includes components with different diameters. The second upper column and the second lower column are accommodated in the inner cavity of the locking base and connected to the locking base via a second spring. The second upper column can extend out from the inner cavity of the locking base. The locking base and the second lower column can be sleeved on the outer periphery of the base and can move along the second direction of the base. The second column can move along the third direction of the locking base. The second upper column can be inserted into the thumb ring in the annular operating handle. The mounting part includes a connecting rod and an elastic open ring disposed at one end of the connecting rod. The other end of the connecting rod is connected to one end of the base. The elastic open ring can be connected to the operating handle of the endoscope.

[0007] Preferably, a first clamping plate assembly is provided on the other side of the base, and a second clamping plate assembly is provided on the other side of the locking base. The first clamping plate assembly and the second clamping plate assembly can be used to clamp the tubular part of the tubular operating handle.

[0008] Preferably, the first clamping plate assembly is positioned on the opposite side of the fixing platform.

[0009] Preferably, the first clamping piece assembly consists of a pair of first arc-shaped clamping pieces extending outward from the base, which enclose a first clamping space; the second clamping piece assembly consists of a pair of second arc-shaped clamping pieces extending outward from the locking base, which enclose a second clamping space.

[0010] Preferably, the bracket portion further includes a limiting boss disposed at the other end of the base, the limiting boss being able to limit the movement of the locking base along the second direction of the base.

[0011] Preferably, a pair of first windows are symmetrically arranged in the second direction of the locking base, and a second window is arranged in the third direction of the locking base; the second upper column can pass through the second window and extend to the outside of the locking base, and a pair of third windows are arranged in the second direction of the second lower column, and the base can pass through both the first window and the third window; when the second column is compressed or released in the third direction relative to the locking base, the first window and the third window can coincide or be misaligned.

[0012] Preferably, the elastic open ring is made of an elastic material.

[0013] To achieve the above-mentioned objectives, this utility model also provides the following technical solutions:

[0014] An endoscope system includes an endoscope, diagnostic and therapeutic instruments, and the aforementioned endoscopic diagnostic and therapeutic instrument fixation bracket. The diagnostic and therapeutic instruments can be inserted into the body through the instrument channel of the endoscope, and the mounting part of the endoscopic diagnostic and therapeutic instrument fixation bracket detachably mounts the diagnostic and therapeutic instruments onto the endoscope.

[0027] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings. In this specification, the same or similar reference numerals indicate the same or similar components. The following description of the embodiments of this utility model with reference to the accompanying drawings is intended to explain the overall inventive concept of this utility model and should not be construed as a limitation thereof.

[0028] Furthermore, in the following detailed description, numerous specific details are set forth for ease of explanation to provide a thorough understanding of the embodiments disclosed herein. However, it will be apparent that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and apparatuses are illustrated to simplify the figures.

[0029] like Figures 1 to 8 As shown, the endoscopic diagnostic instrument fixation bracket 100 of this embodiment includes a bracket portion 110, a clamping portion 120, a locking portion 130, and a mounting portion 140. It should be noted that in this embodiment, "first direction," "second direction," and "third direction" are directions that intersect perpendicularly in pairs.

[0030] The bracket portion 110 of this embodiment includes a base 111, one end of which is connected to the mounting portion 140. In some preferred embodiments, a limiting boss 112 may be provided at the other end of the base 111. The limiting boss 112 can limit the movement of the locking portion 130 (or locking base 131) along the second direction of the base 111, preventing the locking portion 130 from disengaging from the base 111 during movement. As an example, the base 111 may be a generally rectangular structure.

[0031] The clamping part 120 of this embodiment includes a fixed platform 121, a guide rail 122, a pair of first springs 123, a pair of first posts 124, and a pair of limiting balls 125. The fixed platform 121 is positioned near one end of the base 111, that is, relatively close to the position where the base 111 connects to the mounting part 140. A channel is formed inside the fixed platform 121 along its first direction, through which the guide rail 122 passes. After the guide rail 122 passes through, the first springs 123, the first posts 124, and the limiting balls 125 respectively pass through its two ends. That is, the first springs 123 are sleeved on the outside of the guide rail 122 and positioned between the fixed platform 121 and the first posts 124, while the limiting balls 125 are positioned at both ends of the guide rail 122. The first posts 124 can be inserted into a pair of symmetrically arranged finger rings 210 in the annular operating handle 200. The first posts 124 can slide along the guide rail 122. The first spring 123 is positioned between the first column 124 and the fixed platform 121. Its elasticity pushes the first column 124 away from the fixed platform 121 (or the center of the guide rail 122). This structure ensures reliable clamping when the first column 124 is inserted into the pair of finger rings 210 of the annular operating handle 200. The limiting ball 125 prevents the first column 124 from detaching from the guide rail 122 under the action of the first spring 123.

[0032] The locking part 130 of this embodiment includes a locking base 131, a second column 132, and a second spring 133. The locking base 131 has an inner cavity. The second column 132 includes a second upper column 1321 and a second lower column 1322 with different diameters. The second lower column 1322 can be accommodated in the inner cavity of the locking base 131 and is connected to the locking base 131 by the second spring 133. The second upper column 1321 can extend out of the inner cavity of the locking base 131. The locking base 131 and the second lower column 1322 can be sleeved on the outer periphery of the base 111 and can move along the second direction of the base 111. The second column 132 can move along the third direction of the locking base 131 due to the structure of the second spring 133. The second upper column 1321 can be inserted into the thumb ring 220 in the annular operating handle 200.

[0033] The locking part 130 of this utility model embodiment can move controllably along the base 111 of the support part 110 in a second direction. By moving or stopping the movement of the locking part 130, the operating handle of the diagnostic and therapeutic instrument is moved, thereby controlling and maintaining the functions of the front treatment end of the diagnostic and therapeutic instrument, such as the extension and retraction, opening and closing state of the instrument.

[0034] In some preferred embodiments, a pair of first openings 1311 are symmetrically arranged in the second direction of the locking base 131. These openings allow the base 111 to penetrate the locking base 131 in the second direction, thus achieving a structure that fits around the outer periphery of the base 111, ultimately enabling the locking base 131 to move along the second direction of the base 111. A second opening 1312 is arranged in the third direction of the locking base 131. There is only one opening, which means that the locking base 131 is in a state where one end is open and the other end is closed. The open end allows the second upper column 1321 to extend out of the second opening 131 to the outside of the locking base 131. The second lower column 1322 is provided with a pair of third openings 1323 along its second direction. These openings allow the base 111 to penetrate the second lower column 1322 in the second direction, thus achieving a structure that fits around the outer periphery of the base 111. Ultimately, this allows the second lower column 1322 (or the second column 132) to move along the second direction of the base 111. Due to the elastic connection between the second lower column 1322 and the locking base 131, the second column 132 can be compressed or released relative to the locking base 131 in a third direction. When the second column 132 is compressed, it moves downward along the third direction, and the third opening 1323 of the second lower column 1322 and the first opening 1311 of the locking base 131 change from misalignment to maximized overlap. At this time, the locking part 130 is unlocked, and the locking base 131 can move along the second direction of the base 111 to adjust the distance between the second column 132 and the first column 124. When the compression of the second column 132 is released, the second lower column 1322 moves upward in a third direction under the action of elastic restoring force. The overlap between the third opening 1323 of the second lower column 1322 and the first opening 1311 of the locking base 131 decreases, thus returning to the misaligned state. The lower edge of the first opening 1311 contacts the upper and lower edges of the third opening 1323 and together clamps the base 111. At this time, the locking part 130 is locked, and the locking base 131 is restricted to the outer periphery of the base 111. Locking and unlocking are achieved by controlling the overlap between the first and third openings through a scissor-like overlapping mechanism.

[0035] The mounting part 140 of this embodiment includes a connecting rod 141 and an elastic open ring 142 disposed at one end of the connecting rod 141. The other end of the connecting rod 141 is connected to one end of the base 111. The elastic open ring 142 can be connected to the operating handle of the endoscope. In some preferred embodiments, the elastic open ring 142 is made of an elastic material, thus accommodating endoscopes of various sizes and improving the compatibility of the fixing bracket of this embodiment.

[0036] In some preferred embodiments, a first clamping assembly 151 is provided on the other side of the base 111, and a second clamping assembly 152 is provided on the other side of the locking base 131. The first clamping assembly 151 and the second clamping assembly 152 can be used to clamp the tubular portion 310 of the tubular operating handle 300. Preferably, the first clamping assembly 151 is located on the opposite side of the fixing platform 121.

[0037] In some preferred embodiments, the first clamping plate assembly 151 is a pair of first arc-shaped clamping plates extending outward from the base 111, the first arc-shaped clamping plates enclosing a first clamping space. The second clamping plate assembly 152 is a pair of second arc-shaped clamping plates extending outward from the locking base 131, the second arc-shaped clamping plates enclosing a second clamping space. Both the first clamping space and the second clamping space can be used to clamp the upper part 311 and the lower part 312 of the tubular portion 310.

[0038] This utility model embodiment also provides an endoscope system, which includes an endoscope (not shown in the figure), diagnostic and therapeutic instruments, and the aforementioned endoscopic diagnostic and therapeutic instrument fixation bracket. The diagnostic and therapeutic instruments can enter the body through the instrument channel of the endoscope, and the mounting part of the endoscopic diagnostic and therapeutic instrument fixation bracket detachably mounts the diagnostic and therapeutic instruments onto the endoscope.

[0039] The endoscopic diagnostic instrument fixation bracket provided in this embodiment is compatible with both annular and tubular operating handles. The annular operating handle includes a pair of symmetrically arranged finger rings and a thumb ring, while the tubular operating handle has a tubular portion.

[0040] The ring-shaped operating handle is fixed by a three-point support method consisting of a pair of first columns and a second column. The pair of finger rings and the thumb ring of the ring-shaped operating handle are embedded in the three independent columns, and the distance between the second column and the first column is adjustable.

[0041] For the fixing method of the tubular operating handle, an arc-shaped clamping method is adopted. The tubular part enters the clamping space of the clamping piece through the opening of the arc-shaped clamping piece. The two wings of the opening are elastic and can conform to the outer diameter of the tubular part.

[0042] The following is a brief introduction to the use of the fixation bracket of this endoscopic diagnostic and therapeutic instrument.

[0043] The lower part of the endoscope operating handle is inserted into the flexible open ring through its opening. The two wings of the flexible open ring are elastic and conform to the outer diameter of the endoscope operating handle. The flexible open ring is stably connected to the base end of the support via a connecting rod, allowing the support to move with the endoscope operating handle. After the front treatment end of the endoscope is inserted into the body through the instrument channel of the endoscope, the operating handle of the instrument is mounted on the support.

[0044] State 1: The ring-shaped operating handle is fixed to the front of the support. A pair of first posts of the support are housed within a pair of finger rings of the ring-shaped operating handle, and a second post of the support is housed within the thumb ring of the ring-shaped operating handle. Pressing down on the second post allows the locking part to slide on the base of the support, controlling the extension or opening / closing function of the front treatment end of the diagnostic and therapeutic instrument. Releasing the second post stops the locking part from sliding on the base of the support, maintaining the extension or opening / closing state of the front treatment end of the diagnostic and therapeutic instrument.

[0045] State 2: The tubular operating handle is fixed to the front of the support, with the upper part of the tubular operating handle positioned within the first arc-shaped clamp of the support, and the lower part positioned within the second arc-shaped clamp of the support. Pressing down the second column allows the locking part to slide on the base of the support, thereby controlling the extension or opening / closing function of the front treatment end of the diagnostic and therapeutic device. Releasing the third column stops the locking part from sliding on the base of the support, thereby maintaining the extension or opening / closing state of the front treatment end of the diagnostic and therapeutic device.

[0046] At the end, the endoscopist removes the operating handle of the endoscopic diagnostic instrument and disconnects the support from the endoscope.
