Description

FIELD OF THE INVENTION

The present invention relates to medical device holders, and more particularly to devices for positioning and holding medical instruments, such as surgical syringes.

BACKGROUND OF THE INVENTION

Surgical syringes are commonly used by physicians, nurses, and other hospital personnel for a variety of purposes. In certain surgical procedures, syringes are used to deliver fluids gradually and/or intermittently over a period of time via a single puncture wound in a patient. Such procedures typically require the surgeon or other staff member to maintain the position of the surgical syringe. However, it is undesirable to manually hold a syringe, as it can be difficult to maintain a steady hand. Unnecessary movement can result in displacement of the needle, or can cause injury to the patient. In addition, it is desirable to free-up the surgeon's, or other staff member's, hands to allow them to perform other functions during the time between injections.

Accordingly, there is a need for a surgical syringe holder that is effective to maintain a syringe in a relatively fixed position over a period of time.

SUMMARY OF THE INVENTION

The present invention provides a medical device holder for holding a surgical device, such as a surgical syringe, in a relatively fixed position. In one embodiment, the device includes a hollow elongate member having a first end, a second end, and an inner lumen extending therebetween for receiving a medical device. At least one end cap member is removably mated to at least one of the first and second ends of the elongate member, and includes a central opening formed therein. The central opening in at least one of the end cap members has a size configured to assist in retaining at least a portion of a medical device within the inner lumen of the elongate member.

In one embodiment, the medical device holder includes a first, distal end cap member removably mated to the first, distal end of the elongate member, and a second, proximal end cap member removably mated to the second, proximal end of the elongate member. A variety of mating elements can be provided for removably mating the first and second end cap members to the elongate member. By way of non-limiting example, each end cap member can include at least one threaded member formed on an inner surface thereof, and the first and second ends of the elongate member can include at least one corresponding threaded member. Alternatively, the first and second end cap members can be mated to the elongate member by an interference fit, or a positive mechanical engagement.

In other aspects, the medical device is a surgical syringe having a barrel, a needle extending distally from the barrel, and a plunger extending proximally from the barrel. The elongate member preferably has a generally cylindrical shape and is adapted to receive at least a portion of the barrel of the syringe. The central opening in the distal end cap member can have a diameter smaller than a diameter of the barrel of the syringe to prevent the barrel from extending through the distal end cap member. Conversely, the central opening in the proximal end cap member preferably has a diameter greater than the diameter of the barrel of the syringe to allow the barrel to extend therethrough. In an alternative embodiment, the central opening in the first, distal end cap member and the central opening in the second, proximal end cap member can each have substantially the same diameter, and the diameter is greater than a diameter of the barrel of the syringe.

In another embodiment, the medical device holder can include at least one gripping member, such as an o-ring, disposed between at least one of the first and second end cap members and the first and second ends of the hollow elongate member. The gripping member is effective to grip the barrel portion of the syringe to hinder movement of the syringe with respect to the elongate member.

A system for holding a medical device is also provided and includes a medical device holder having a hollow elongate member, proximal and distal end cap members removably mated to proximal and distal ends of the elongate member, and a medical device removably disposed within the inner lumen of the hollow elongate member. The proximal and distal end cap members each include a central opening extending therethrough, and at least one of the end cap members is effective to retain the medical device within the hollow elongate member.

In a preferred embodiment, the medical device is a surgical syringe having a barrel disposed within the inner lumen of the hollow elongate member and through the central opening in the proximal end cap member, a needle extending from the distal end of the barrel and through the central opening in the distal end cap member, and a plunger extending from the proximal end of the barrel. The central opening in the distal end cap member can have a diameter smaller than a diameter of the syringe barrel, and the central opening in the proximal end cap member can have a diameter greater than a diameter of the syringe barrel. In a preferred embodiment, the central opening in each of the proximal and distal end cap members are substantially the same, and the diameter is larger than a diameter of the syringe barrel.

In use, the second, distal end cap member is mated to the medical device holder. The syringe is then inserted through the proximal end of the elongate member to insert the needle through the central opening in the distal end cap member and position the distal end of the barrel against the inner surface of the distal end cap member. The first end cap member can then optionally be mated to the proximal end of the elongate member.

In other aspects, the medical device holder can be configured to either allow movement or limit movement of the surgical syringe with respect to the elongate member. In one embodiment, the surgical syringe is slidably disposed and movable within the inner lumen of the hollow elongate member such that the barrel portion of the syringe can slidably extend through the proximal end cap member. The device having this configuration, preferably includes a connector element adapted to mate to a rigid surgical retractor arm.

In another embodiment, the medical device holder can include a gripping member, such as an o-ring, effective to grip a portion of the medical device to hinder movement of the device with respect to the elongate member. The gripping member can be disposed within the elongate member, within one or both end cap members, or between one or both end cap members and the elongate member. The gripping member is preferably configured to extend into the lumen of the elongate member and/or end cap members to effectively limit the inside diameter of the lumen. In this configuration, the device preferably includes a connector element adapted to mate to a flexible surgical retractor arm.

In yet another embodiment, a medical device holder is provided having a substantially hollow elongate member having a distal end, a proximal end, and a lumen extending therebetween defined by an inner lumen wall. A compressible gripping member is disposed over at least a portion of the inner lumen wall, and is effective to effectively reduce an inner diameter of the lumen. The device further includes connector element disposed on at least a portion of an outer wall of the elongate member. The connector element is effective to mate the elongate member to a support member. The gripping member can be, for example, an o-ring or a compressible sleeve. In an exemplary embodiment, the gripping member is compressible between a first inner diameter when no medical device is disposed within the lumen of the elongate member, and a second, larger inner diameter when a medical device having an outer diameter greater than the first diameter is disposed within the inner lumen of the elongate member.

In another embodiment, the device includes first and second members, each having a generally elongate extension with first and second ends, an upper grasping member mated to the first end, and a lower grasping member mated to the second end. A mating element is formed on at least one of the first and second members for pivotally mating the first member with respect to the second member. In use, the first and second members are pivotally movably between a first, open position, and a second, closed position wherein the upper and lower grasping members of the first and second members are adapted to engage and support a medical device.

The first and second members of the medical device holder can include an actuating member for effecting movement of the first and second members with respect to each other. In one embodiment, the actuating member can be opposed first and second handles mated to the first and second members. A compressive force applied to bring the first and second handles in contact with each other causes opening of the first and second members. The device can optionally include a biasing element for biasing the first and second members to one of the open or closed positions. The device can also include a locking element effective to lock the first and second members in the open or, more preferably, in the closed position, wherein the upper and lower grasping members of the first and second members are adapted to engage and support a medical device.

The upper and lower grasping members of each of the first and second members can have a variety of configurations, but preferably each grasping member has a generally semi-cylindrical shape and is adapted to grasp a generally cylindrical medical device, such as the barrel of a surgical syringe. The grasping members can include a resilient surface disposed on an inner, gripping surface of each grasping member. Alternatively, or in addition, each grasping member can include a high friction surface disposed on the inner, gripping surface thereof.

The first and second members can be mated together using a variety of configurations, but preferably the generally elongate extension of each member includes an outwardly extending portion having a bore disposed therethrough. A pin member is removably disposed through each bore in the first and second members, thereby mating the members, yet allowing pivotal movement of the members with respect to each other. In one aspect, the pin member can include proximal and distal ends. The proximal end preferably has a diameter larger than a diameter of the bore in each of the first and second members to prevent the proximal end of the pin member from extending through each bore. The distal end of the pin member can be adapted to mate to a support member, and can, for example, include a groove formed therein and adapted to mate with a retaining ring to prevent the pin member from being removed from the bore formed in each of the first and second members. The distal end of the pin can also include a locking element effective to lock the first and second members in one of the open or closed positions. The locking element can be, for example, threads formed on the distal end of the pin member for mating with complementary threads formed on the support member.

DETAILED DESCRIPTION OF THE INVENTION

The present invention provides a medical device holder for positioning and holding a medical device in a relatively fixed position. The medical device holder is particularly useful for holding surgical syringes over a length of time, thereby allowing the surgeon and/or other medical personnel to perform other functions during the time between injections. A person having ordinary skill in the art will appreciate that, while the device is described for use as a surgical syringe holder, the device can be configured to hold a variety of medical instruments. [0029]
FIG. 1 illustrates one embodiment of a [0030] medical device holder 10. As shown, the device 10 generally includes a substantially hollow elongate member 12 having a proximal end 14, a distal end 16, and an inner lumen 18 formed therein. A first end cap member 20 is removably and replaceably disposed on the proximal end 14 of the elongate member 12, and a second end cap member 22 is removably and replaceably disposed on the distal end 16 of the elongate member 10. In use, one or both end cap members 20, 22 of the medical device holder 10 can be effective to assist in retaining at least a portion of a medical device within the inner lumen 18 of the hollow elongate member 12. For example, the distal end cap member 22 can be configured to retain a portion of a medical device within the inner lumen 18 of the hollow elongate member 12, while the proximal end cap member 20, on the other hand, can be configured to allow a medical device to be slidably disposed therethrough. In a preferred embodiment, both end cap members 20, 22 are configured to allow a medical device to be slidably disposed therethrough.
The hollow [0031] elongate member 12, as shown in more detail in FIG. 2, includes a proximal end 14, a distal end 16, and an inner lumen 18 extending therebetween. The outer wall of the elongate member 12 can be formed from a substantially solid structure, or it can optionally include one or more openings formed therein and extending into the inner lumen 18. By way of non-limiting example, the elongate member 12 can include at least one slot 13 extending along the length of the elongate member 12 to allow visual access to a medical device disposed within the inner lumen 18 of the elongate member 12.
The [0032] elongate member 12 can have virtually any shape and size, but preferably has a shape and size configured to hold a pre-selected medical device. As shown in FIGS. 1-3, the elongate member 12 has a generally cylindrical shape and is configured to receive a surgical syringe 50, or at least the barrel portion 52 of a surgical syringe 50. While FIGS. 1-3 illustrate a generally cylindrical shape, the elongate member 12 may have alternative shapes such as, for example, a square, rectangular, polygonal, or ovoid shape. Moreover, the elongate member 12 can include a variety of surface features, cut-out portions, indentations, or other features which define the shape.
The length l[0033] _eand diameter d_eof the elongate member 12 can also vary, but should be configured to receive at least a portion of a barrel of a surgical syringe 50. The diameter d_eis preferably greater than the diameter of a surgical syringe barrel to allow the barrel to be slidably disposed within the inner lumen 18 of the elongate member 12. The diameter d_ecan, however, be configured to hinder rotational movement of a syringe 50 with respect to the elongate member 12. The length l_eof the elongate member 10 is preferably less than the length of a barrel of a surgical syringe. In an exemplary embodiment, the elongate member 12 has a length l_ein the range of about 1 and 10 inches, and a diameter d_ein the range of about 0.1 and 100 mm.
The proximal and distal ends [0034] 14, 16 of the elongate member 12 are each adapted to mate with an end cap member 20, and thus can include a mating element 24 a, 24 b formed thereon. In one embodiment, the mating elements 24 a, 24 b may be formed from one or more threads disposed around an outer surface of the elongate member 12 adjacent the proximal and distal ends 14, 16. The threads 24 a, 24 b are configured to mate with corresponding threads 26 a, 26 b formed on each end cap member 20, 22. A person having ordinary skill in the art will appreciate that a variety of alternative mating elements can be used to connect the end cap members 20, 22 to the elongate member 12. For example, the proximal and distal ends 14, 16 of the elongate member 12 can include an annular flange or a groove formed thereon for mating with a corresponding groove or annular flange, respectively, formed on each end cap member 20, 22. Other suitable mating techniques include, but are not limited to, an interference fit and a positive mechanical engagement.
The [0035] medical device holder 10 can include one or more end cap members 20, 22, which are also shown in more detail in FIG. 2. The end cap members 20, 22 can have a variety of shapes and sizes, and preferably include a central opening 28 a, 28 b, or inner lumen, extending therethrough for receiving a at least a portion of a medical device disposed within the inner lumen 18 of the elongate member 12. The distal end cap member 22 can be formed integrally with the elongate member 12, or alternatively it can be removably and replaceably mated to the distal end 16 of the elongate member 12. The proximal end cap member 20 is optional depending on the intended use.
Preferably, each [0036] end cap member 20, 22 has a size and shape which allows each member 20, 22 to be removably and replaceably mated to the proximal and distal ends 14, 16 of the elongate member 12. In one embodiment, each end cap member 20, 22 has a generally cylindrical shape. The end cap members 20, 22 can also optionally include a knurled outer surface, as shown in FIG. 1, for facilitating gripping of the end cap members 20, 22. In use, the distal end cap member 22 can be adapted to assist in retaining a medical device within the inner lumen 18 of the elongate member 12.
In one embodiment, the [0037] central opening 28 a, 28 b in the proximal and distal end cap members 20, 22 each have an inner portion pp_i, dp_i, a middle portion pp_m, dp_m, and an outer portion pp_o, dp_o. The inner portion pp_i, dp_iof each end cap member 20, 22 can include a mating element 26 a, 26 b formed therein for mating with the proximal and distal ends 14, 16, respectively, of the elongate member 12. In an exemplary embodiment shown in FIG. 2, the mating elements 26 a, 26 b are formed from at least one thread configured to engage corresponding threads 24 a, 24 b formed on the elongate member 12. As previously stated, a variety of mating techniques can be used to connect the end cap members 20, 22 to the elongate member 12. The middle portion pp_m, dp_mof each end cap member 20, 22 preferably has a diameter d_mabout the same as, or greater than, the diameter d_eof the inner lumen 18 of the elongate member 12. Thus, when each end cap member 20, 22 is mated to the elongate member 12, the middle portion p_mand the inner lumen 18 of the elongate member 12 form a substantially contiguous, smooth surface.
The outer portion pp[0038] _o, dp_oof each end cap member 20, 22 can vary depending on use. In one embodiment, the distal end cap member 22 can be configured to prevent at least a portion of a medical device from extending therethrough. For example, where the medical device is a surgical syringe 50 having a barrel 52 disposed within the elongate member 12, as shown in FIG. 3, the outer portion dp_oof the distal end cap member 12 can have a size which allows a needle 54 extending distally from the barrel 52 of the syringe 50 to extend through the central opening 28 b, yet prevents the barrel 52 of the syringe 50 from extending therethrough. As a result, the distal end cap member 22 is effective to assist in retaining the barrel 52 of the syringe 50 within the inner lumen 18 of the elongate member 12. The diameter dd_oof the outer portion dp_ois thus preferably smaller than the diameter dd_mof the middle portion dp_mand/or the diameter d_eof the inner lumen 18 of the elongate member 12. The proximal end cap member 20, on the other hand, can have middle and outer portions pp_m, pp_ohaving diameters substantially the same as, greater than, or smaller than the diameter d_eof the inner lumen 18 of the elongate member 12.
The [0039] medical device holder 10 can optionally include one or more gripping elements configured to hinder movement of a medical device with respect to the elongate member 12. The gripping element can be provided, in addition to or as an alternative to the end cap members 20, 22, to assist in retaining a portion of a syringe within the elongate member 12. The gripping element can be positioned anywhere within the medical device, and should be effective to grip a portion of a medical device disposed within the inner lumen 18 of the elongate member 12. In one embodiment, the gripping element can be fixedly or removably disposed within the elongate member 12, disposed within the end cap members 20, 22, or disposed between the end cap members 20, 22 and the elongate member 12.
In the embodiment shown in FIG. 3, the gripping element is an o-[0040] ring 34 disposed between the end cap members 20, 22 and the elongate member 12. In an exemplary embodiment, the o-ring is disposed within the middle portion p_mof one or each end cap member 20, 22. The o-ring can have a variety of shapes and sizes, and can be formed from a variety of high friction and/or compressible materials. Preferably, at least a portion of the o-ring extends into the space defined by the lumen 18 of the elongate member 12 and/or the end cap members 20, 22 to effectively limit the inside diameter of the lumen 18 or end cap members 20, 22. As a result, the o-ring is effective to grip the barrel portion 52 of the surgical syringe 50 to hinder or prevent movement of the syringe 50 with respect to the elongate member 12.
A person having ordinary skill in the art will appreciate that the [0041] medical device holder 10 can alternatively or additionally include a variety of other gripping elements or similar type of frictional elements disposed within the inner lumen 18 of the elongate member 12, or within the end cap members 20, 22, for preventing or hindering movement of a syringe with respect to the elongate member 12. For example, one or more high friction strips can be placed along the length, or around the circumference of the inner surface 18 of the elongate member 12. Alternatively, or in addition, the elongate member 12 can include surface features that are adapted to engage the surgical syringe, or a compressible sleeve disposed over at least a portion of the inner lumen wall 18 and compressible between a first inner diameter when no medical device is disposed within the lumen 18 of the elongate member 12, and a second inner diameter when a medical device having an outer diameter greater than the first diameter is disposed within the inner lumen 18 of the elongate member 12. In another embodiment, a compressible gasket can be placed within lumen 18, extending along all or a portion thereof.
In use, the [0042] medical device holder 10 is preferably assembled by attaching the distal end cap member 22 to the distal end 16 of the elongate member 12. An o-ring can optionally be placed between the distal end cap member 22 and the elongate member 12 prior to mating the two members. A syringe, or other medical device, is then inserted into the proximal end 14 and the inner lumen 18 of the elongate member 12. The needle of the syringe 54 extends through the central opening 28 b in the distal end cap member 22. Depending on the diameter dd_oof the opening 28 b in the distal end cap member 22, a distal end surface of the barrel 52 can abuts the distal end cap member 22. The device 10 can be utilized in this configuration.
Alternatively, or in addition, the proximal [0043] end cap member 20 can be mated to the proximal end of the elongate member 12. As shown in FIG. 3, the barrel of the syringe 52 can extend through the central opening 28 a in the proximal end cap member 20, and thus is slidably movably with respect to the elongate member 12. An o-ring member 34 can optionally be positioned between the proximal end cap member 20 and the elongate member 12 prior to mating the end cap member 20 to the elongate member 12.
As shown in FIG. 4, the [0044] medical device holder 10 is preferably configured to mate with a surgical support member, such as a surgical retractor arm 70, for maintaining the position of the medical device holder 10 with respect to a patient. Thus, as shown in FIGS. 3 and 4, the device holder 10 can include at least one connector 42, 44 for mating with a complementary connector 72 (FIG. 4) formed on a support member 70. A person having ordinary skill in the art will appreciate that virtually any type of connector can be used to mate the medical device holder 10 to virtually any type of surgical support member, such as a table support or a retractor arm.
In an exemplary embodiment, the [0045] medical device holder 10 is configured to mate with either a rigid retractor arm (not shown) or a flexible retractor arm 70. In certain surgical procedures where a syringe is inserted at a single puncture wound over an extended period, it can be desirous to allow the syringe to move in conjunction with the patient's breathing. Thus, where a rigid surgical retractor arm is employed, the medical device holder 10 is preferably configured to allow the syringe 50 to move with respect to the elongate member 12. Alternatively, where a flexible surgical retractor arm is employed, the medical device holder 10 is preferably configured to prevent movement of the syringe 50 with respect to the elongate member 12. As a result of either configuration, the syringe 50, or alternatively the flexible retractor arm, is allowed to move in conjunction with the patient's breathing.
FIGS. [0046] 5-10 illustrate another embodiment of a medical device holder 100. As shown in FIG. 5, the medical device holder 100 generally includes opposed first and second members 102 a, 102 b, each having a generally elongate extension 104 a, 104 b, and at least one grasping member 106 a, 106 b, 108 a, 108 b. A mating element 110, shown in FIG. 6, is formed on, or disposed between, the first and second members 102 a, 102 b for pivotally mating the first and second members 102 a, 102 b. In use, the first and second members 102 a, 102 b are movable between a first, open position (not shown), and a second closed position in which the grasping members 106 a, 106 b, 108 a, 108 b are adapted to engage and support a medical device, such as a surgical syringe 150. The first and second members 102 a, 102 b can also each include an actuating member 112 a, 112 b for effecting movement of the first and second members 102 a, 102 b with respect to each other.
While FIG. 5 illustrates [0047] medical device holder 100 engaging and supporting a surgical syringe 150, a person having ordinary skill in the art will appreciate that the medical device holder 100 can be used to support a variety of medical devices.
The first and [0048] second members 102 a, 102 b are each shown in more detail in FIGS. 7 and 8, respectively. As shown, each member 102 a, 102 b includes a generally elongate extension 104 a, 104 b having a first, proximal end 104 a ₁, 104 b ₁, and a second, distal end 104 a ₂, 104 b ₂. An upper grasping member 106 a is mated to the proximal end 104 a ₁of the elongate extension 104 a of the first member 102 a, and an opposed, upper grasping member 106 b is mated to the proximal end 104 b ₁of the elongate extension 104 b of the second member 102 b. Likewise, the medical device holder 100 can include a lower grasping member 108 a mated to the distal end 104 a ₂of the elongate extension 104 a of the first member 102 a, and an opposed, lower grasping member 108 b mated to the distal end 104 b ₂of the elongate extension 104 b of the second member 102 b. In use, the upper and lower grasping members 106 a, 106 b, 108 a, 108 b are adapted to engage and support a medical device 150 disposed therebetween.
The [0049] elongate extensions 104 a, 104 b can have virtually any shape and size, but should be configured to support the grasping members 106 a, 106 b, 108 a, 108 b in a position in which the grasping members 106 a, 106 b, 108 a, 108 b are effective to engage and support a medical device 150. A person having ordinary skill in the art will appreciate that the first and second members 102 a, 102 b of the medical device holder 100 can be constructed without an elongate extension 104 a, 104 b. Moreover, each member 102 a, 102 b can include one or more grasping members mated thereto or formed thereon.
Each grasping [0050] member 106 a, 106 b, 108 a, 108 b can have a variety of shapes and sizes, but preferably each member 106 a, 106 b, 108 a, 108 b has a shape and size configured to engage a medical device, such as a surgical syringe 150. The grasping members 106 a, 106 b, 108 a, 108 b can be formed integrally with the elongate extension 104 a, 104 b or some other portion of the first and second members 102 a, 102 b, or alternatively can be mated thereto using a variety of techniques known in the art. Moreover, the grasping members 106 a, 106 b, 108 a, 108 b can be adjustably mated to the medical device holder 100 to allow each grasping member 106 a, 106 b, 108 a, 108 b to be positioned properly to facilitate engagement and support of a medical device. In an exemplary embodiment shown in FIGS. 7 and 8, each grasping member 106 a, 106 b. 108 a, 108 b has a generally semi-circular shape and includes an inner, concave gripping surface 106 a _i, 106 b _i, 108 a _i, 108 b _i, and an outer convex surface 106 a _o, 106 b _o, 108 a _o, 108 b _o,. The inner, gripping surface 106 a _i, 106 b _i, 108 a _i, 108 b _iof each grasping member 106 a, 106 b, 108 a, 108 b can optionally including a resilient, compressible, and/or high friction surface disposed thereon for facilitating engagement of the medical device disposed therebetween.
